I can't make it working, move line up or down doesn't work. When I reset keyboard for VS and applay scheme for Resharper it ask me for this :
and if I take first selection , then alt + up switch me between methods, if I use second selection then this combination does not effects.
Alt+Up is not a ReSharper shortcut to move a line. It most likely belongs to the Productivity Power Tools extension, that has a feature to move one or more (selected) lines.
Personally, I don't like this feature in PPT, since it will just move the line(s), regardless of their scope, causing compilation errors. I much rather use ReSharper's feature of moving blocks of code up or down, by pressing Ctrl + Shift + Alt + ↑/↓ or ←/→ - when on the beginning of the line, it will move the entire line or block of code, but can also be used to move entire methods, change the order of parameters, etc.
I ended up resetting my Resharper shortcuts. Then when prompted with the dialog, chose Use Visual Studio Commands for the Alt+Up & Alt+Down shortcut.
You could also set this manually in Tools > Options > Environment > Keyboard. Search for "MoveSelectedLines" and then assign Alt+Up/Down to the appropriate command.
On my machine with Resharper 2016.1 it makes a difference on what position the cursor is located:
cursor located from 1st to last character on the line: the shortcuts work as described by Igal Tabachnik
cursor located on white spaces before 1st characters of the line the shortcuts are ignored.

I have a new installation of Visual Studio Code (default configuration, with vim keymap). I want to use the command "add selection to find next match". I think this is equivalent to how multicursors work in sublime text and vim (with an extension), or Atom (find and replace: select next).
When I try to run the command directly by using Ctrl D it does not work, taking me to the last line in the file. This might be some kind of conflict that might be easy to solve.
More interestingly, when I run the command from the command palette Ctrl Shift P.
The first time selects the word I am at (well done!)
The second time selects the next occurrence of that word, but loses the selection, moving the two cursors right after the two first occurrences of the word.
The third time and next times nothing happens, the selection was lost in the previous time.
How to get the awesome normal behaviour that other editors have?
PD: I have now confirmed that this behavior is not present without the vim keymap, may they be compatible somehow?
Ctl + D is a default Vim keybind that scrolls the window down in the buffer. This is expected behavior for the Vim extension, and you should disable the mapping if you wish to use it to run the VSCode command "Add Selection To Find Next Match".
To do this, open the extension's setting by clicking File > Preferences > Extensions. From there, choose the Vim extension and select the option to Configure Extension Settings. There will be an option called Handle Keys, where you can enter JSON data to send certain key combos back to VSCode (and there's another option to turn off all Ctl + Letter combos, called Use Ctrl Keys). You can find some examples of such data on the extension's Marketplace page. Below is the snippet of code that I added to my settings.json file to get Ctl + D back.
"vim.handleKeys": {
"<C-d>": false
}
From my testing, it looks like changing this setting also fixes the behavior when using the Command Palette. It might be a bug, but who cares when you are most likely just going to use Ctl + D anyway. :)
If I have a line with 8 spaces (yes, spaces, not tabs) and some text...
x=3;
... and my cursor is placed after the semicolon, when I hit Enter it positions the cursor under the x. In other words it indents it 8 positions. If I then hit backspace it positions the cursor after the semicolon! I expect the backspace to take me back 1 space on the new line.
In Editor>Code Style > Java, Tab size = 1, Indent = 0, Continuation indent = 0. N.B. that if I try to set Tab size to 0 it's 1 next time I bring up that dialog, so 0 is apparently not acceptable to Android Studio, even though I see it suggested in several S.O. questions.
In Editor > Code Style I UNchecked Detect and use existing file indents for editing and now if I hit Enter with the cursor after the semicolon it positions the cursor 4 spaces in the from the right, in other words it still indents, just not as much.
N.B, that after making these settings I did a File > Invalidate Caches / Restart.
I don't want any automatic indenting. When I hit Enter I want it to position the cursor at the first position of the new line, and when I hit backspace I want it to go back 1 position, just like an ordinary "dumb" editor. How do I turn off all automatic indenting in Android Studio?
Android studio tries its best, like most IDEs, to help you organize your work and make it successful. It is normal, but of course, there is a way to disable it.
Note: Your project can be really messy when disabling this, if you want to properly indent a block of code, highlight it then press CTRL+ALT+L, this will indent the highlighted for you.
So, to disable it, press CTRL+ALT+S, this will open settings. Now, go to the Editor tab at your left, where you then go to General, then Smart Keys. You should see a "Backspace" part. Over there, there will be a dropdown menu, click that then select the "Disabled" option. (Settings>Editor>General>Smart Keys> )
Is this just the normal, expected behavior of A.S.?
I'd say it's the normal expected behavior of any IDE to indent correctly while you are typing. Your next line is supposed to start at the same position than the previous and if you close a bracket A.S. will automatically unindent it once.
Now on your topic :
To make your backspace key just delete the space you can go to : Settings -> Editor -> General -> Smart Keys -> Backspace -> Unindent and put 'Disabled' instead of 'To proper indent position'
Resharper has (or had) a feature allowing autocompletion to be triggered when pressing semi colon, so I don't have to press enter to autocomplete and then semi colon.
I can't find how to enable this feature in IntelliJ/Android Studio. Is there any way to do this?
IntelliJ has something similar, but it works for space, dot and semicolon (maybe other characters). Not sure if the behavior can be modified if you want IntelliJ to autocomplete only on semicolon. Here is how you enable it:
Go to Settings/Editor/General/Code Completion
Enable Insert selected variant by typing dot, space, etc.
Sometimes I have to write Java class where I need to define multiple fields of the same type. For example, I know that I will need to duplicate private final String on the next 4 lines.
Is it possible to spawn multiple carets in IntelliJ editor, so I can type on mutliple lines at the sime time?
IntelliJ IDEA 14.1 & 15
You can press Alt + Shift and using the mouse left click you can put many carets.
E.g.:
will become
typing "added" only once.
If you want to have a continuous vertical line, it's enough to press Alt + drag your mouse vertically. If there are lines with a length lower than the current position, the vertical line will be broken (carets will be placed at the end of every line) if "Allow placement of caret after end of line" is disabled (in File > Settings... > Editor > General > Virtual Space).
Another way to add a continuous vertical line is to hit Ctrl twice and then press up or down arrow key (supported in JetBrains 2016.X products, and possibly earlier).
If you cannot get the shortcuts working, check what they're currently assigned to under Settings > Keymap Add or Remove Caret, Clone Caret Above and Clone Caret Below. If they look right and you're on Linux, your window manager may be capturing the combination, e.g., for Alt + window drag operations.

I think "Column Selection Mode" could help you. You can enable it in the context menu in the editor. Then you can select multiple lines and type same text at once.
Column Select
For Windows, you can use CTRL+CTRL(Hold)+↑ / ↓. For Mac, replace the CTRL with ⌘.
Change Multi-caret Hotkey
To add a custom Keymap, CTRL+SHIFT+A, type keymap and click on the one with Settings as subtext. Search for Clone Caret Above and Clone Caret Below.
I mapped mine to ALT+SHIFT+↑ / ↓.
Bonus
Try holding combinations of CTRL, SHIFT, and arrows for improved selection power.
On Windows:
You can enable the Column Selection Mode (Alt + Shift + Insert)
And then Shift + ↑ / ↓ can select multiple columns
Hit Esc to go back to single cursor
Add/remove a caret: Alt + Shift + Mouse Click
Remove all carets: Esc
As for now(2018.9), you just:
Press middle mouse key to create a four-rows-high caret
Type what you want
Or,
Create the first line,
Press the "Duplicate entire line" key combination to create a new, identical line.
By the way, I think "multiple caret" should be like carets enabling me to edit different locations which are not necessarily vertically aligned. In Sublime Text you can press Ctrl and click. And in IntelliJ you can only "Clone caret up/down", that is to say, they are vertically aligned, which is not flexible.
I'm relatively new to the world of Vim. I've been learning my way around it but have yet to find a practical purpose to enter visual mode.
What are some scenarios when visual mode is especially useful?
Are there actions that can only be performed from within visual mode?
I use visual mode when I want to highlight a section of text. I start by typing v in standard mode, which then enables the visual mode. Then I use the arrow keys to move the cursor. This causes the text between my starting point and the current cursor location to be highlighted. Once you select a section of text like this, entering a command (e.g. search/replace) in command mode (by typing :) will only affect the selected area.
Another useful visual command is shift+v (visual line). This does the same as above, but it selects entire lines at a time instead of individual characters.
When you want to comment a block of text.
In command mode :
Shift + v
,ctrl +v,
j or k,
I , #(comment
character) and then Esc
Vim inserts the comment character to
the start of the block..
is when I am using Gvim, I find it much easier to copy data
to the clipboard through visual mode.
In command mode :
Shift + v
, j or k ,
" , +
,y
Here + is the clipboard
register
This to me is much more legible that using markers
is for manual indenting
Shift + v,
Shift + > for
moving to the right.
Shift + < for
moving to the left. .
repeats
this is fun :-)
One of the nice things about visual mode is that, because of Vim's focus on modality, you can perform most of the commands that you are used to (such as search/replace with :s, d to delete text, or r to replace text) while also seeing exactly what will be affected -- this allows you to determine the exact scope of whatever you are doing.
Furthermore, as someone else mentioned, you can easily insert a prefix (like a comment character or, say, & for alignment or \item in LaTeX) by selecting the first character of each line in visual block mode (ctrl+v), pressing I to insert before the first character, typing in whatever you want to insert, and then Escing back to normal mode.
The last kind of visual mode is visual line (Shift+v), which allows you to quickly select a number of lines. From there, you can change their indentation using > or < (prefix this with a number to indent by that many tabs), use d or y to delete or copy those lines, use zf to create a new fold from those lines, or use any other selection-based command.
Finally, there are a lot of other cool things you can do with visual mode, including gv to reselect your last visual[line/block] mode selection, gU to convert a visual selection to uppercase or gu for lowercase, and many more.
In addition to the other (great) answers, it's an easy way to define scope for an action. For example, to limit a search & replace to a specific method...
Say you have this code:
function foo() {
abc();
while (1) {
def();
abc();
}
}
You can place the cursor on any of the braces or parentheses and press v, %, :, s/abc/xyz/g and your search & replace will have a defined scope in which the action will occur.
Visual mode is useful if you want to apply a command to a section of text that isn't easily described as a primitive movement command. You can select some text in visual mode with a complex sequence of movements and then apply a command to that selection.
I often find myself using visual-block mode (Ctrl + v) more than any of the other visual modes.
You can easily remove indentation, comments, etc. once you are aware of this mode. In my experience, this is often faster than figuring out how to form an equivalent search-and-delete statement.
You can also add indentation (or comments as Cherian stated) by selecting a block of text and pressing I, typing whatever you want to add, and pressing Esc (note: you may need to redraw the screen (e.g. by moving the cursor) to see the effects of this).
I haven't seen the following mentioned, probably because they're subtle.
1 - Less hassle with the unnamed register
Whenever you copy (yank) some text, and then want to d to change some other text, e.g., diw to "delete inner word," Vim will place the deleted text into the unnamed register. Then if you try to paste, it will just paste the deleted text right back unless you do "0p to paste from the 0 register.
But with visual mode, you can just do something like viwp and don't have to mess with registers.
So, for comparison, to copy and replace inside some parens:
yiw -> move somewhere -> vi(p
vs
yiw -> move -> ci(<C-r>0p
yiw -> move -> "_di(p
yiw -> move -> di("0P
Note: this also works for deleting text and pasting it back over a text object. See here.
2 - Jumping to parts of a text object
If you want to jump to the beginning or end of a text object, you can select it in visual mode and press o. For example, va" to select anywhere inside quotes, and then press o to jump to the matching quotes, kind of like % for matching brackets.
