VIM key bindings issues

When I long press hjkl in vim mode, the cursor just move once, it should continue moving until I release keys, just like in vim. I am using OS X version, and I've set long pressing for repeating like this: http://apple.stackexchange.com/questions/46361/keyboard-no-longer-repeats-keys-when-held-down

I use vim command "viw" a lot for select a word witch the cursor is inside, but this command is not working in haroopad.
