I've suggested something already in the comments. Now, as far as simple mappings go, for normal mode you can always do the simple remapping of main keys.
nnoremap : >>
nnoremap ; >>
for example, for indent (I'm on Croatian keyboard layout here ... where the < and > characters are, I have ; and : ... I'm sure you understand the example). You can analogly remap all your local characters with parenthesis, brackets or any other essential characters.
