is it possible to mapping Alt-hjkl in Insert mode?

Question

before describing my problem, I\'d list the env. applications here:

OS:linux 2.6.37-ARCH  (archlinux i686)
vim: 7.2.436
Terminal emulator: urxvt (with 256co         


        

Answer 1

For arrow keys:

Start by viewing the key code your terminal is sending to vim:

$ sed -n l
^[[1;9D 

In the above example, i ran the sed command and pressed Alt + Left.

The ^[[1;9D is the escaped sequence being sent to vim, so we can user that for our mapping.

Add this to your .vimrc

map <Esc>[1;9D :tabn<CR>

Now we can cycle through vim tabs by using Alt + Left

Answer 2

It's easier to map what your key combination does. Alt+something generally results in a character, differently from Ctrl+something.

For example, on my Mac Alt plus hjkl generates ˙∆˚¬. So:

imap ˙ <Left>
imap ∆ <Down>
imap ˚ <Up>
imap ¬ <Right>

would do it.
