Re: Map CTRL-[ to CTRL-T, is it possible

Thanks Tony.

But I'm too used to use the Esc key to get out of Insert mode.

I will have to figure out another pair of keymaps to jumo between tags.

Cheers

P.S. You can regain <Esc> function by mapping something else to it, e.g. with

        inoremap ² <Esc>

(assuming that, as on my keyboard, the key left of the 1 gives the
exponent-2) will let you get out of Insert mode by hitting that. Or
use for the {lhs} any key that suits your fancy and doesn't cfonflict
with something that you would use in Insert mode.

Best regards,
Tony.
