There is a way in webstorm to comment or uncomment a specific line or selected block of source code with shortcut?
I try to use CTRL + / but doesn't work for me

Try to use Ctrl+Slash or Ctrl+Shift+Slash for block comment
If this doesn't work show in your Setting -> Keymap -> Search comment
Use CTRL+/, but with the / located on the numpad.
The question remains why commenting with / (the one besides .) does not work (it does not for me, either).
Ctrl + / ==> To comment/uncomment a line .
Ctrl + Shift + / ==> To comment/uncomment block of code.
Ctrl + Y ==> To delete a line.
On a Mac with an extra keyboard it is CMD + Numpad's /.
The one on the native Macbook keyboard I did not get to work.
Check this post as well: Intellij comment shortcut opens help tab on the Mac menu bar
On Windows with a German keyboard layoout the default keyboard shortcut for the comment lines action Ctrl+/ conflicts with the bookmark shortcut Ctrl+7. You need to remove the keyboard shortcut for bookmarks in order to get this to work.
#Note Shortcut IntelliJ IDEA
Ctrl + / => comment or uncomment a line -> //
Ctrl + shift + / => comment or uncomment block of code -> /**/
Ctrl + y => delete a line
Ctrl + d => duplicate a line
If Ctrl + Shift + / doesn't work , try Ctrl + Shift + Num Pad /.
You can check the exact configuration in settings->keymap.
Commenting out each line of selected code for Mac users without numpad would have to add a keyboard shortcut:
Navigate to settings: Preferences > Keymap > Main menu > Code
Double click on Comment with Line Comment
Insert your shortcut, for example: cmd + shift + 7 would be interpreted as shift + cmd + 7 but works the same.
I have an AZERTY keypad in French, so this was the answer for me :
Ctrl + Shift + / on the numpad
Because / out of the numpad was detected as :, even with Caps Lock on.
You can check how the keystrokes are actually detected by IntelliJ in :
On Windows :
Settings > Keymap > click on the icon of Magnifying glass with cubes (tooltip is "Find Actions By Shortcut"). In the little tooltip that opens, you stroke the keys and observe the registered results.
On Ubuntu :
Settings > Keymap > click on the icon of Keyboard, right next to the search input (tooltip is "Find Actions By Shortcut"). In the little tooltip that opens, you stroke the keys and observe the registered results.
You need to activate this option:
'Settings' > 'Keymap' > 'Use national layouts for shortcuts (requires restart)'
As said before on Mac Montery 12
on Idea 2020.3
CMD + NumPad /
or from Action dialog:
It is necessary to switch to the English layout
its possible to use inellij IDEA by the way you customized before with an IDE like VisualStudio
Settings -> KeyMap -> Choose your old IDE its a grate! feature life saver :)
try ctrl + shift + 7 or num lock and then ctrl + /
control + / (this is the mathematical one which is located on the numbad)
Is it possible to get back to my previous caret position after i do a quick fix for create Field on a variable?
test = new String();
My caret is on "test" and i press ALT+ENTER -> create field 'test'
caret goes up to the top of the class and i can edit the Type then i press TAB to get to the name of the variable but after that i only can press ENTER and i don't go back to my line in the code.
I tried ENTER, TAB, ESCAPE.
Refactoring to Field works fine.
Use Intellij shortcut for navigating to last cursor location.
Mac: Alt + Command + Left Arrow
Win: Alt + Control + Left Arrow
Similarly, you can also cycle forward to the last cursor location using
Mac: Alt + Command + Right Arrow
Win: Alt + Control + Right Arrow
On Windows, and I think Mac, holding alt + left click on a section of code when paused in the debugger will evaluate the expression and show the value in a tooltip. It's much more convenient than alt + f8 and ctrl + alt + 8.
In Linux Mint, holding alt and clicking doesn't do anything (I've disabled Mint's "Special key to move and resize windows").
Is there a way to map it to alt + left click, or a different key combination to evaluate an expression by clicking on it?
Found it mapped to ctrl + alt + shift + left click under Quick Evaluate Expression as a Mouse Shortcut.
Settings -> keymap, change from "Default for XWin" to "Default"
In FireFox, I'm constantly using the Ctrl + 1-9 shortcut to switch tabs. Basically Ctrl + 1 will take me to the first tab, Ctrl + 2 will take me to the second one and so on.
Is there an equivalent for this shortcut in IntelliJ IDEA?
UPDATE:
You can now assign keyboard shortcuts to navigate to the specific tab number:
Original obsolete response:
There is no such feature in IDEA, however you can use Alt + Arrows and Ctrl + E (Recent Files) to navigate between tabs.
Other handy actions from the Go To menu:
Back / Forward (Ctrl + Alt + ←/→)
Last Edit Location (Ctrl + Shift + Backspace)
Another option is to use the GoToTabs third-party plug-in:
The plugin adds menu actions allowing you to go to a specific tab. You
can of course assign keyboard shortcuts the individual actions and for
example achieve the behavior known from other editors/IDEs where you
can switch between tabs with alt+num.
The IDE itself still doesn't support it but I've created a plugin (GoToTabs) that will add "Go to tab #" actions you can assign keyboard shortcuts to (e.g. ctrl+1).
you also can use ctrl + tab to active switcher
after ctrl + tab and keep holding ctrl for other operations
ctrl + number is for bookmarks feature.
Since this is one of the first hits when Googling this, note that as of IntelliJ IDEA 2018.3 EAP this is now possible. From the feature request tracker:
In upcoming 2018.3 EAPs you're welcome to assign shortcuts you need for new actions in the group 'Other', see a screenshot. With these actions you can select tab1..tab9 and also the last tab.
To accomplish this:
Go to Keymap in Preferences
Search for "select tab"
Individually assign Command+<number> to each of the tab numbers mappings
You can use this short cut on mac
Shift + Command + { or }
Not sure what you asking is possible but Navigate as below in intellij idea (13) to switch tabs in one level,
File
└────Settings
└─────────Keymap
└────── Editor Tabs
Where yo can map for actions "Select Next Tab" and "Select Previous Tab", under "Editor tabs" in keymaps. Following is an example for emacs keymap.
cmd+shift+[ - go to previous tab
cmd+shift+] - go to next tab
Actually, there is an option, pressing Alt + Tab a switcher will pop up.
Like this:
[
If you are using IntelliJ's IdeaVim plugin, the vim style shortcut works as well:
gt, go to next tab
gT, go to the previous tab
1gt, go to the first tab
2gt, go to the second tab
3gt, ....
If a tab has a number with an underline like this example, you can use Alt + 9 to switch to it. But not all tabs have a underlined number.
MacOS:
Next tab: ⇧ + ⌘ + ]
Previous tab: ⇧ + ⌘ + [
if you use ideavim, you can use num+gt to go to the specific tab. for example, 2gt lead you to the second tab.
Keymap -> Other -> Tabs.
Then setup what you want

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
