How to use tabs with vim in the Linux "screen" program?

Question

When I use the Linux screen program, pressing the tab key will move between multiple screen windows. But when I want to press Tab to add blank space in a file using vim, it is useless, and will move to another screen. How can I use Tab with vim in screen?

EDIT: (taken from comments)

I have this keybinding in my .screenrc file:

escape ^Ii

And if I remove that, the Tab key works again.

Answer 1

The problem is your escape ^Ii entry in the .screenrc file.

In many/most terminal emulators, ^I (CtrlI) is the same key code as the Tab key (ASCII 0x11, aka "TAB" or "Horizontal Tab").

So the only solution is to choose a different escape key for use in screen.
