In IdeaVIM, if I extract a variable and want to name it, it seems like I'm in visual mode (the name of the variable is highlighted), yet I can't figure out a way to change what's highlighted. Here's an image:
If I type c, it doesn't do anything. If I type cc, it changes the whole line. Basically, it acts like I'm in command mode yet the name is highlighted as if it's in visual mode. What I want to do 99% of the time is change this word. Yet, the cursor is annoyingly one character after the word so ciw doesn't change it.
What's a convenient way to rename this variable? I've normally done hciw. I'd prefer that "extract variable" put me directly into insert mode, though.
It's a little counterintuitive, but the easiest thing to do is just immediately hit i to enter insert mode, then start typing the new name, and it will replace the highlighted text.
The problem, as I see it, is that vim is modal and vanilla IntelliJ is also modal, and what you have here is the interaction of two sets of modes. To understand the IntelliJ modes, try turning off IdeaVIM with ^Z and use the extract variable refactoring. Notice how if you start typing right away, what you type replaces the selected text, but if you move the cursor first and then start typing, what you type is inserted at the cursor. Now add IdeaVIM to the mix: once you are in insert mode, IntelliJ's behavior kicks in.
See VIM-274 for a request to change this behavior and some discussion of alternatives.
For "Extract Variable" once you've got to the point where it's suggesting names:
What always works is pressing Escape, b, cw and then typing the new name.
Sometimes you can press b right away, but often that puts me into visual mode for some reason, so pressing Escape is guaranteed.

In intellij 2022.1, I use Ctrl+Shift+R to bring up the Replace in Files window - it shows 100+ matches in 40+ files. The search string and the replace string differ in only one character, for example: this.bar.is.fooed and this.barf.is.fooed. I only need to replace certain instances based on nearby text.
I'm in the groove, clicking the Replace button, checking the next entry, clicking, checking, ... and thinking my brain can keep things straight (it can't; neither can yours:-) I'm halfway through when I realize the last few replaces were wrong.
How can I undo them? Ctrl+Z is grayed out. This related SO question doesn't say and neither does the JetBrains documentation!
Use Local History to revert the changes.
Undo/redo is not supported for Replace dialog, vote for the related request.
Intellij keeps making my life difficult. I decided to go to the bottom with it today and create a new keyboard mapping for mac using the program ukulele.
By default, Mac will output all kinds of weird characters when you hold down the option key. Now, since I never use any of those, I prefer to use them for shortcuts and using ukelele you can create a new keyboard layout. The program works fine. It is good.
Now, shortcuts are not filled on the keyboard, and in the learning phase, you will try some that are not working, or assigned.
When this happens, Intellij outputs weird characters instead. Characters such as for instance for the combo option + r. Same for e, t and so on.
This does not occur in chrome, the terminal, TextEdit or any other program.
Intellij seems to realize the combo does not result in anything and decides to put out the same character for all those keys.
As you see in the picture below from the macOS build-in keyboard viewer, the keys are not mapped (option being held down) at all.
Note, that only Intellij so far outputs these characters.
Do this in VS 2010 with VB.NET:
On a blank line, type anything that isn't a variable, property, method, etc. I will use woo as an example.
Hit Enter or move the cursor up or down a line.
VS will add parenthesis to the end of it, turning it into woo().
Annoying, isn't it? Now insert foo in front of woo(), separated by a space like this: foo woo().
Move the cursor up or down (don't use Enter). VS turns it into foo(woo()), somehow drawing the conclusion that you want to pass woo() through foo(). What gave it that idea?
I know that the IDE isn't a text editor, but there are many times when I will want to paste in some text from a business requirements document or even some SQL and then comment it out after the fact. c# is great for this since it never assumes that I am trying to do anything, but the VB.NET IDE ends up parsing the holy love out of whatever block of text I paste into it and I end up having to edit out everything it added in.
Why does it do this? Can I tell it not to?
Unselect Pretty listing (reformatting) of code. You can find this under: Tools -> Options -> Text Editor -> Basic -> VB Specific
I have comments that gets balloon (PEP 8: Line too long ... > 120)
I wish there was a command that will wrap the lines with few keystrokes.
Right now, even if I type Alt+Enter and press enter on Reformat file, nothing actually changes. Is there a setting or plugin I could use to accomplish the formatting easily?
Under the Edit menu, there is a Fill Paragraph option, which does what I believe you want. You can assign a key command to this in Preferences, under Appearance & Behavior -> Keymap (search for "fill").
Personally, I choose first stroke Esc, second stroke Q, because that's what I've always used in Emacs...
Firstly, reformatting won't work, not in Python at least, where whitespace is important. PyCharm's "Wrap when typing reaches right margin" option is what you're looking for. Now this will not work when you copy and paste code, but in the places where it gives you trouble, just press enter, and it will work.
To be able to auto-reformat comments (and code, for that matter) to honor a right margin after the fact, go into Project Settings under Code Style and then further under Python. Click the Wrapping and Braces tab, and check the "Ensure right margin is not exceeded" checkbox.
Now if you select a region of lines and then run the Code/Reformat Code... command, PyCharm will do its best to wrap the comments or code appropriately.
You will probably have to do some tweaking of the results to suit your stylistic taste. For example, I wish PyCharm would do aggressive filling of text in block comments, at least optionally so.
PyCharm will not reformat code such that it becomes invalid Python, so sometimes it will still leave a line longer than the margin (120 or whatever you set under Project Settings/Code Style/General).
With recent PyCharm this now is located at "Editor -> Code Style", with the checkbox named "Wrap on typing"
The Screenshot shows PyCharm version 2016.2.1 Professional.
Updated Answer:
Use "soft wraps." You can search for it in the help bar.
View > Active Editor > Use Soft Wraps
It won't work for existing text or text that's copied in, but will for any newly typed text.
I'm using coderush with vs 2008. coding in VB.net.
I don't see any evidence of Intellassist, all i see is the usual VS intellisense.
Is this normal? Preferred? Do most people leave the defaults or do most/some turn off vs's intellisense?
Does intellassist somehow agument intellisence?
thanks

I see CodeRush Intellassist as an extension of Visual Studio Intellisense and not its replacement or anything else. Intellassist completes the text at the editor caret position with an in-scope identifier and may include other suggestions, such as physical file path completion or enumeration elements completion (which is not actual for Visual Basic).
To use Intellassist, just write code as you normally would. When Intellassist senses one or more suggestions matching the code you've entered so far, the best suggestion will be displayed to the right of the editor caret.
Once Intellassist is active, you have several options:
Press Enter to accept the highlighted suggestion. If you have the case-sensitive option turned off, Intellassist will ensure the entire suggestion is properly cased to match the declaration.
Press Shift+Enter to accept a portion of the suggestion. Shift+Enter accepts from the caret to the character preceding the next uppercase letter in the suggestion. For example, if "AllowMultipleSelections" was the suggestion, and "al" had been typed in, pressing Shift+Enter successive times would cause the selection to shift as follows:
Shift+Enter is useful when you need to create a new variable name that is similar to a portion of an existing suggestion, or when you want to quickly access a different but similarly-named suggestion (differing only in the latter portions of the text). You can press Shift+Enter to move the selection right, and then start typing to get other suggestions.
If more than one entry is suggested you can cycle forward and backward through the suggestions by pressing the Tab and Shift+Tab.
Press the Delete key to cancel the suggestion.
Do nothing for a few moments and Intellassist will hide the suggestion.
If the text you've entered is a code template that you want to expand, just press Space or ; to expand the template normally.
Continue typing (narrowing down the suggestion list or ultimately ignoring all suggestions).
Intellassist is highly configurable. You can specify whether case-insensitive suggestions should be made, and also change a host of other options.
