在omap映射中使用alt键

Question

I'm unable to use the Alt key in omap mappings in Linux. For eg.

nmap <A-w> w

works properly and behaves identically to w . However, the following doesn't.

omap <A-w> w

doesn't work as expected in Ubuntu but does in Windows. What am I missing here?

EDIT: I'm using gvim but my menubar has been disabled so doesn't open the gvim Menu.

Answer 1

EDIT: Realized that this was happening because the key is mapped to the key in Ubuntu Unity. This was somehow interfering with my Vim setup. Once I changed that key, everything is working as expected.

Answer 2

Your omap is ok. Since you mentioned that you work with gvim. I guess when you press <Aw> , it will trigger the menu of gvim. If this is your problem, you could:

:set wak=no

to solve it.

:h 'wak' for detail
