Can anyone give me some suggestion or link of all controls of Android Studio keyboard shortcuts?
Preferences > Keymap will show you all the keyboard bindings.
A couple helpful hints to help you find features:
You can search actions by name; on MacOS the keybinding is Command+Shift+A. You can start typing the name of a command and it will show you all matching commands and their key bindings if they have one. That's really convenient for looking up the key shortcut for something if you have a hint of what it's called.
In most dialogs/windows there's a search box, and you can usually just start typing to start a search. It's especially good for preferences, where there are so many options that are hard to find.
to assign a keyboard shortcut, you need to navigate to
file --> setting --> keymap --> search and than right click and add keyboard shortcut --> in first stroke
you can add/change like
ex:
you want to assign Cntl + w than use Cntl with w
