I use SAS Enterprise Guide and Teradata Studio Express to code for my day job. WindowsOS.
I use CTRL + / shortcut to comment lines of code out in both apps. Suddenly, this shortcut has stopped working. I've checked all my keyboard and Code Shortcut Key settings in both apps and nothing seems out of place!
All other shortcuts seem to work in both apps, common ones I use like CTRL+C (copy), CTRL+X (cut), CTRL+V (paste) etc
I've got no idea why the 'comment out' shortcut is unable to register. Anyone else encounter this same annoying issue?
CTRL + : will pack your line in /* and */
If you have selected a range, Enterprise Guide will do that with every line from which you selected any character.
CTRL + Shift + : will unpack them
You just have to define it again.
Go to Tools-->options-->Enhanced Editor Keys
Select the Command "Comment the selection...." and press Assign keys
within "Press new shortcut key:" enter the ctrl + : key and press assign
I want to use AutoHotKey to disable Alt+F4 when they are pressed within 0.05 seconds of each other. Otherwise, I'd like it to work as normal.
Explanation:
My Lenovo Yoga 2 Pro has alternate functions for the function keys.
For example: "F3" is mapped to volume+, "F4" is mapped to "close active window"
There are two modes:
Old-school mode: F3 just acts as F3, and you must hold Fn+F3 key to activate volume+
New-school mode: Pressing F3 activates volume+, and Fn+F3 will do the normal F3.
In either mode, I run the risk of closing my active window when I go to use volume+ because they are too close, which is very problematic. Note that AutoHotKey cannot detect the Fn key, thus I cannot use that to solve my issue.
The image below shows the AutoHotKey Key History tool. In New-school mode, I typed "asdf" and then pressed "F4" which is "close active window". You can see this actually simulates ALT+F4, and there is a very short duration between ALT and F4...
I'm thinking that I could disable this "close active window" function by having AutoHotKey interrupt an ALT+F4 combo when there is less than 0.05 seconds between the two keys. Can this be done?
Edit:
In response to Blauhirn's code, here is the original, edited for a shorter wait duration, (from 50 to 10). It works most of the time, though 1/10 times the window is still cosed:
~alt::
hotkey, alt, off
hotkey, !F4, doNothing, on
sleep, 10
hotkey, !F4, doNothing, off
while(getKeyState("alt"))
sleep, 1
hotkey, alt, on
return
doNothing:
return
Here is a change I thought would fix my focus issue by sending a 2nd Alt when the "close active window" was detected:
doNothing:
send {LAlt}
return
However, the 2nd Alt is not sent. It IS sent when the delay is above 40ish, however I find that is way too long, and in turn it interferes with my manual use of Alt+F4.
Have you tried using simply
F4::return
? Maybe this will override the Lenovo action for F4
Other than that, here are the two approaches I can think of:
Disabling the ALT+F4 standard win hotkey by default. Adding a custom hotkey for a delayed F4
!F4:: ; by default:
doNothing: ; this is a label (see GoSub)
return ; == do nothing
~alt:: ; alt was pressed
sleep, 50 ; wait 50 milliseconds
if(!getKeyState("alt")) ; if alt is NOT pressed down anymore, exit
return
else ; (else is actually unnecessary here)
hotkey, !F4, close ; Add new AltF4-hotkey
return
close:
winclose, A ; close the Active window
return
~alt up:: ; alt is being released
hotkey, !F4, doNothing ; remove the new AltF4 hotkey and go back to custom standard behaviour: do nothing.
return
it still triggers Alt, which usually leaves me in the menu of the active window (File, Edit, View, etc), or if typing within a textarea (such is this), it will remove typing focus.
well yes. If you decide to keep the lenovo keys, I don't think there is a way to prevent it. As you suggested, sending ALT again should solve the problem
using Input, after ALT has been pressed. Input blocks user input for a configurable time, as long as the V option is used.
(3. disabling your Lenovo Yoga 2 Pro special keys. If you need the F3 function, you can do that in AutoHotkey e.g. using send {volume_up}
Just read about Assigning a Keyboard shortcut to a button in an Access. By using & in front of Caption of any control.
For example if want to assign Alt + N to a button, in Caption Property put &New
But this only assigns Alt.
Here are my Questions
& is to assign Alt, which is the symbol for Ctlr?
What about and Shift and Function Keys like F3?
Can these be assigned?
Is there any VBA code, or Property to add keyboard shortcuts?
For keys like F1, F2, F3 so on, you may code it directly in the VBA code, with a case/ or if else statement by checking for each vbKeyF1, vbKeyF2 etc with a KeyPress, KeyDown event trigger.
Take a look at these two references for using Autokey Macro as well.
Run an Access macro by using a keyboard shortcut.
Assigning Auto Keys for Aligning Controls.
I know that Ctrl + N is to find classes and it is very useful. But what about methods?
ctrl + F12 (cmd + F12 on macOS) will show all members of the current class in a popup window and let you pick up one. It works exactly like the ctrl + o shortcut in eclipse, much faster than ctrl + alt + shift + n
Windows : ^ ctrl + F12
MacOS : ⌘ cmd + F12
Above commands will show the functions/methods in the current class.
Press ⇧ SHIFT TWO times if you want to search both class and method in the whole project.
Ctrl + Alt + Shift + N allows you to search for symbols, including methods.
The primary advantage of this more complicated keybinding is that is searches in all files, not just the current file as Ctrl + F12 does.
(And as always, for Mac you substitute Cmd for Ctrl for these keybindings.)
Android Studio on Mac
Command + Option + O
Opens up the Symbol lookup that you can jump to most of the methods/functions in your currently opened document.
Intellij IDEA 2017.3.4 - 2018.2 (Ultimate) on OSX
CMD + fn + F12
will show all members of the current class in a popup window, then you can search method in that class.
BUT, this answer is depends on your Keyboard setting. If your keyboard setting in
System Preferences > Keyboard > Use all F1, F2, etc. keys as standard function keys
is selected, then the shortcut becomes
CMD + F12
CTRL + F12 brings up the File Structure navigation menu, which lets you search for members of the currently open file.
IntelliJ IDEA Version 12.13 Ultimate Edition:
Macs:
command + option + shift + N
or on Menu -> Navigate > Symbol ...
Slightly beside the actual question, but nonetheless useful: The Help menu of Intellij has an option 'Default Keymap reference', which opens a PDF with the complete mapping. (Ctrl+F12 is mentioned there)
If you just want to look for methods:
On mac OS X 10.5+ binding, it is Alt + ⌘ + O
By Default XWin Key binding, it is Shift + Ctrl + Alt + N
You can also press double SHIFT then, you can search anything (not only method, but also class, files, and actions)
It is worth adding that if you want to search for a method of a class, you can use a . (dot) between the class and method name inside of either the search everywhere or search symbols dialog. This even works with IDEAs usual search benefits. For example, you can search for LDT.now and LocalDateTime::now will pop up as a result. (As long as you are searching All Files and not just Project Files).
If you click on a method, you can do Ctrl + B to go to that method's declaration. Similar to F12 in MS Visual Studio.
To Find the actions build in the IDEA(reindent, create new, ...) you can use
CRTL+SHIFT+A
then type indent for example and ENTER.
If I need navigate to method in currently opened class, I use this combination: ALT+7 (CMD+7 on Mac) to open structure view, and press two times (first time open, second time focus on view), type name of methods, select on of needed.
Intellij v 13.1.4, OSX
The Open Symbol keyboard shortcut is
command+shift+s
Ctrl + Shift + Alt+ 7 after selecting the method
I tried SHIFT + SHIFT and ALT + CMD + O
But I think the most powerful and easy to use feature is find in all files CMD + SHIFT + F.
Choose regex and write .*partOfMethodName.*\( and it shows all places and can see the actual source code in place without going to that specific file.

How to select columns in Editors and IDEs to columnar delete, insert or replace some characters ?
Editors:
Atom
Notepad++
Kate
VIM
Sublime
Emacs
Textpad
Emerald Editor
UltraEdit
MCEdit
jEdit
Nedit
IDEs:
NetBeans
Eclipse
Visual Studio
IntelliJ IDEA
Flash Builder
Aptana Studio
Notepad++, Visual Studio, and some others: Alt + drag.
vim: Ctrl + v or (bizarrely enough) Quad-click-drag. In windows: Ctrl + Q (since Ctrl + V is the standard for paste)
In Kate toggle Ctrl + shift + B .
In Netbeans 7.1 can select columns (Rectangular Selection) with Ctrl + shift + R . There is also a button in the code editor available.
This is how rectangular selections look like:
Eclipse used to need a column mode plugin to be able to select a rectangular selection.
Since Eclipse 3.5, you just need to type Alt+Shift+A: see its News and Noteworthy section. (On OS X it's Option-Command-A.)
Or activate the 'Editor Presentation' action set ( Window > Customize Perspective menu) to get a tool bar button for toggling the block selection mode.
AmbroseChapel adds in the comments:
This is a toggle.
Columnar selection is a mode you enter and leave: in other words, Eclipse switches into a mode where all mouse selections have to be columnar and you stay in that mode until you switch back (by using the same command again).
It's not like other editors where columnar selections are enabled only while certain keys are down.
In vim column visual mode is Ctrl + v. If that is what you meant?
SublimeText 2, 3, and 4
Using the Mouse
Different mouse buttons are used on each platform:
OS X
Left Mouse Button + Option
OR: Middle Mouse Button
Add to selection: Command
Subtract from selection: Command+Shift
Windows
Right Mouse Button + Shift
OR: Middle Mouse Button
Add to selection: Ctrl
Subtract from selection: Alt
Linux
Right Mouse Button + Shift
Add to selection: Ctrl
Subtract from selection: Alt
Using the Keyboard
OS X
ctrl + shift + ↑
ctrl + shift + ↓
Windows
ctrl + alt + ↑
ctrl + alt + ↓
Linux
ctrl + alt + ↑
ctrl + alt + ↓

You didn't explicitly state emacs, but since you've highlighted lots of editors...
In emacs, you can use rectangles for this, where a column is a rectangle of width 1.
To create a rectangle, mark the top-left and bottom-right of the rectangle (where the bottom-right mark is one to the right of the further right point included in the rectangle. You can then manipulate via:
C-x r k
Kill the text of the region-rectangle, saving its contents as the "last killed rectangle" (kill-rectangle).
C-x r d
Delete the text of the region-rectangle (delete-rectangle).
C-x r y
Yank the last killed rectangle with its upper left corner at point (yank-rectangle).
C-x r o
Insert blank space to fill the space of the region-rectangle (open-rectangle). This pushes the previous contents of the region-rectangle rightward.
M-x clear-rectangle
Clear the region-rectangle by replacing its contents with spaces.
M-x delete-whitespace-rectangle
Delete whitespace in each of the lines on the specified rectangle, starting from the left edge column of the rectangle.
C-x r t string RET
Replace rectangle contents with string on each line. (string-rectangle).
M-x string-insert-rectangle RET string RET
Insert string on each line of the rectangle.
In IntelliJ IDEA, you can switch the selection mode with Alt + Shift + Insert combination. You can also column select by keeping the middle mouse button (i.e. the scroll wheel button) pressed and dragging.
on Kate
Ctrl + Shift + B also allows you to add more columns by simply clicking anywhere and paste it.
I used this when saving text files I copied from Google Translate as a side-by-side view.
This feature is not available in older versions of Netbeans (up to 7.1) and the plugin is not supported anymore.
A plugin is now available for NetBeans 6.9.
In TextMate with the mouse: start a selection and keep alt pressed while you move the cursor.
Without the mouse: first select normally using ⇧ and arrows then hit alt and move the cursor.
in Notepad++ , you can select a particular column holding ctrl + alt + shift and then left click mouse button and drag to select.
In TextPad:
With the mouse, Left-Click + Alt + Drag. Note that if you first use Alt, and then Click-and-drag, it does not work (at least for me). Ctrl+Alt instead of Alt also Works.
For pure keyboard, no mouse, enable Block Select Mode with Ctrl+Q, B.
Or use the sequence Alt, C, B, to do it via the Configure menu.
Warning 1: if Word Wrap is enabled, then Block Select Mode will not be available (which is somewhat logical). First disable Word Wrap. This was causing me some trouble, and this gave me the answer.
Warning 2: if you mean to insert text in every selected row by typing, you have to use Edit, Fill Block. Other editors let you type in directly.
In Ultra Edit and Crimson (or Emerald) Editor you can enable/disable the column mode with Alt + C
In textpad.
Go to left top of the page.
hold "shift key
Now use right arrow key to select column.
Now click "down arrow" key.
And the entire column will be selected.
jEdit:
With the keyboard: press Alt-\ (Opt-\ in Mac OS X) to toggle between rectangular and normal selection mode; then use Shift plus arrow keys to extend selection. You can switch back to regular selection mode with another Alt-\ (Opt-\ in Mac OS X), if desired.
With the mouse: Either use Alt-\ (Opt-\ in Mac OS X) as above to toggle rectangular selection mode, then drag as usual; or Ctrl-drag (Cmd-drag in Mac OS X). You can switch back to regular selection mode with another Alt-\ (Opt-\ in Mac OS X), if desired.
Actually, you can even make a non-rectangular selection the normal way and then hit Alt-\ (Opt-\ in Mac OS X) to convert it into a rectangular one.
In MCEdit toggle Shift+F3 (ie F13) or F9->Edit ->Mark columns.
P.S. In this case, MCEdit is an editor written for the Midnight Commander.
In Sublime3 (Windows):
Some users may get an inverted screen using the Ctrl+Alt+▲ in windows. To Solve this go to
Preferences->Key Bindings-User
And add these two lines at the end of the file just before closing brackets:
{ "keys": ["ctrl+alt+pageup"], "command": "select_lines", "args": {"forward": false} },
{ "keys": ["ctrl+alt+pagedown"], "command": "select_lines", "args": {"forward": true} }
Or use your own keys.
If you're using Nedit under Cygwin-X (or any platform for that matter), hold down the Ctrl key while selecting text with the left mouse.
Additionally, you can then drag the selected "box" around in an insert mode using the depressed left-mouse button or in overwrite mode by using Ctrl+left-mouse button.
With Nedit you can do several operations with selected column:
CTRL+LEFT-MOUSE -> Mark Rectangular Text-Area
MIDDLE-MOUSE pressed in area -> moving text area with pushing aside other text
CTRL+MIDDLE-MOUSE pressed in marked area -> moving text area with overriding aside text and deleting text from original position
CTRL+SHIFT+MIDDLE-MOUSE pressed in marked area -> copying text area with overriding aside text and keeping text from original position
In Flash Builder (v 4.5 and up), and Aptana Studio (at least v 2.0.5) there is a toolbar button to toggle block select. It is between the 'mark occurrences' and 'show whitespace characters' buttons. There is also a Alt + Shift + A shortcut. Not surprisingly, this is basically the same as for Eclipse, but I'm including here for completeness.
For any editor, you can use the below shortcuts. These shortcuts work for every text area also.
Shift + UpArrow/DownArrow - this will select text line by line
Ctrl + Shift + LeftArrow/RightArrow - this will select text word by word
Ctrl + BackSpace - this will delete text word by word
