perf annotate browser: string search: /?n

Browse Source 
Using the same keystrokes as vim:

/ = search forward
n = search next forward/backwards
? = search backwards

Still needs to continue from start/end when not found, use HOME + / or
END + ? for now.

At some point we need a keybindings file to support ones favourite mode,
erm, like EMACS, etc.

Also we now need a 'h' window with all these keybindings.
