Subject: [PATCH] Wrap in if plus delays on findReplace

onKeyEvent actually happens on multiple events (keypress and keyup at
least)
Wrapped in an if statement now so we only trigger half the time, meaning
half the work, meaning improved usage
Clear any existing timeouts and set a new Timeout to trigger the
findReplace action in 0.5s
This means as you type it's continually clearing & setting timeouts
When you pause typing for more then 0.5s, then it'll trigger the
findReplace
The result is no lag whilst typing and giving find results within
inactivity time only
