I know that in insert mode I could navigate through the document by using the arrow keys or by using Ctrl-o to escape insert mode temporarily. My question is: Is there any other way to navigate through documents instead of using those keys or temporarily escaping?
OK guys, just found a solution for my own question in which I use
imap to map keys in Vim in insert mode.
imap <C-n> <Down> imap <C-p> <Up> imap <C-@> <C-Space>
