I am not sure what keyboard combination I pressed to ended up in this mode, How to fix and exit from this mode of selection?
You probably entered Column Selection Mode via an accidental click in the editor context menu (at least that happens to me occasionally). To exit the mode again, just right-click in the editor and select Column Selection Mode (which will have a check mark in front of it).

In Android Studio, pressing the up an down arrows will change the contrast of the autopopup bar.
Before
After
This also occurs in the default themes. Is there anyway to make the contrast start in the after position, even without pressing any arrows?
The popup is dimmed to indicate that there is no default selection for completion. It depends on context and in some cases the first entry will be selected automatically, while in the other cases you need to select the completion varian with the arrow keys first.
To get the pre-selection work automatically in IntelliJ IDEA and Android Studio enable the Insert selected suggestion by pressing space, dot, or other context-dependent keys option:
In some other cases it may be also necessary to add
-Dide.completion.lookup.element.preselect.depends.on.context=false
in Help | Edit Custom VM Options and restart the IDE.

I usually ctrl+left click to add a new cursor to edit multilines.
But how can I undo a cursor when I made a wrong selection?
The Soft Undo function is what you want here.
It's in the menu as Edit > Undo Selection > Soft Undo, along with an associated option to redo as well.
If you check the menu, it will tell you what the key binding for your platform is set to by default. For example, on Windows it's Ctrl+U.
In Android Studio I changed the tab key function from file > settings > keymap. I chose to remove all other bindings from tab key (mistake!!). And now I can't get auto-complete to work like before.
I want to select an item from the auto-complete pop-up then press tab to complete the word (I think this the default behaviour):
But when I press tab it "completes the sentence" and puts my cursor at the end of the line:
I don't want this, I want to just complete the word and the cursor to stay in place. This is my current configuration for tab:
How do I get the default behaviour back? I really don't want to reinstall Android Studio and it is driving me crazy.
--------------- edit ---------------
"Complete current statement" binding doesn't work:
Now when I press tab nothing happens, it doesn't auto complete at all.
Found the problem. Had to bind "Choose lookup item replace" to tab key to get the default / correct behaviour.
I'm using the IdeaVim plugin for Android Studio, which introduces vim selection semantics and insert/normal mode. When there is a selection, something akin to visual mode is used. However, it is possible to select text while inside either of these modes, and the result is some hybrid insert-visual mode which is highly confusing and leads me to tons of accidental edits (i.e. clicking an editable area sometimes puts me in a mode I don't understand).
If I could completely disable mouse selection (using mouse only to select text, like set mouse=ni), it would make the editor much more comfortable, as this is my preferred vim selection mechanic.
There seems to be no standard option for disabling mouse selection. Is some modification feasible?
I still need to be able to select text using IdeaVim visual mode, i.e. v followed by cursor keys.
The default IntelliJ / Android Studio "Redo" action shortcut is CTRL+Shift+Z and this is a common problem for Windows users.
A bigger problem is CTRL+Y is mapped to the "Delete line" action - and this causes the undo stack to be lost.
To solve this issue, how can the "Redo" shortcut be changed to CTRL+Y in IntelliJ?
Open Settings (press CTRL+ALT+S)
Click Keymap on the left list.
There is a combobox that contains keymaps. Select one of them (default means IntelliJ of course. We can't change any of pre-defined keymap however we can copy, edit and then use the edited one. So) we should copy "default" to change only redo mapping.
Give a new name to your copied keymap.
Right click on:
Main Menu -> Edit -> Redo to click "Add Keyboard Shortcut"
Press CTRL+Y
Click OK
Click "Remove" to "the shortcut is already assigned to other actions. Do you want to remove other assignments?"
If you want to use any "remove line" shortcut also, then go to delete line shortcut and give to it any other shortcut (like 5th step)
Click OK to close settings window.
Change the keymap setting to the Visual Studio, Eclipse, or NetBeans preset.
The settings window can be found under File > Settings. CTRL+ALT+S should work if the shortcut hasn't been changed. In the settings window you should find Keymap under the Appearance & Behavior settings list.
You can configure each editor command to a key combo that you like (as #ismail yavuz mentioned) such as for Redo to CTRL+Y or you can just change the Keymap setting to an editor that you are used to. This might be best if you are in the process of switching to IntelliJ as it is probably the path of least resistance. The default settings for the Visual Studio, Eclipse, and NetBeans keymaps all map Redo to CTRL+Y.
The Principle of least astonishment is strangely violated for Windows users but at least shortcuts is customizable. Because of this command being so contrary to the Windows experience I decided it wasn't worth learning the IntelliJ keyboard when anywhere you're working at you need to, you can quickly change. There are almost no drawbacks to not learning the IntelliJ. Remember that in the keymap menu you can search for a command in the search box or click on the magnifying glass on the right to search by key combo.
Of course neither answer is wrong. Chose your preference.
