Skip over character in insert mode, even at the end of a line

Question

I have this map in my .vimrc:

inoremap <C-space> <C-o>l

So that, eg, if I'm in insert mode:

I can just type <C-space> to move out of parens:

It all works great in the middle of a line. But if that ) were the last character on the line, then the cursor won't move when I hit <C-space>. Which makes sense, because there is nowhere for it move to.

But what I want in this case is for <C-space> to behave as if I'd typed <esc>$a -- ie, gone to the end of the line in normal mode and pressed a to start appending characters.

How can I update my mapping to achieve this special behavior for the end of line case?

Answer 1

Another option is to simply change your mapping to:

inoremap <C-space> <C-o><Space>

<Space> moves forward one character even when at end of line.

Answer 2

If I understand correctly what you want, you can simply set :set virtualedit=onemore and your mapping will start to work even at the line end case.
