Vim move cursor one character in insert mode without arrow keys

This might seem a little too overboard, but I switched to vim and I so happy about the workflow now. I try to discipline myself not to use the arrow keys, as keeping the hands on the alfa-keys all the time is such a big thing when writing. So when I need to navigate I get out of insert mode, move in normal mode and get back in insert mode.

There is an exception where this is actually more disrupting: I use clang complete with snippets and super tab which is great. Except every time I get a function auto completed after I fill in the parameters I am left with the cursor before ) so to continue I have to move the cursor one character to the right. As you can imagine this happens very often.

The only options I have (as far as I know) are : Escla or →, and I am not happy about neither of them. The first one makes me hit 3 keys for just a simple 1 character cursor move, the second one makes me move my hand to the arrow keys. A third option would be to map CTRL-L or smth to →.

So what is the best way of doing this?

//snippets (clang complete + supertab):
foo($`param1`, $`param2`)

//after completion:
foo(var1, var2|)
              ^ ^
              | |
     I am here  |
                 Need to be here

| denotes cursor position

Solution 1:

Map ) to skip over the exisiting ) if it is a closing parenthesis

inoremap <expr> )  strpart(getline('.'), col('.')-1, 1) == ")" ? "\<Right>" : ")"

:h i_CTRL-O execute one command, return to Insert mode.

Ctrl-ol will move you one character to the right then return you to insert mode.

Alternatively some of the bracket plugins allow you to just type the closing bracket ) and they will override the existing one.

Solution 2:

Type the following to find the control keys that are used in insert mode.

:help insert-index

ctrl-b is not used, but you may want to sacrifice some other key.

imap <c-b> <right>

This works to move the cursor right one char. Or map some double char.
