Hello,
Imagine this situation:
- - Someone has a very large history
- - wants to search the history for the word "annoying"
- - he types "a" ..... waits some seconds for the history to redraw
- - he types "n" ..... waits some seconds for the history to redraw
- - he types "n" ..... waits some seconds for the history to redraw
- - he types "o" ..... waits some seconds for the history to redraw
- - he types "y" ..... waits some seconds for the history to redraw
you know what i'm talking about, right?
So i wrote a patch that uses a timer for the history filter.
After applying my patch it will be possible to type in the complete word
"annoying" without having the history redraw after each character. this is
because the history waits exactly one second after a keypress, then it
redraws it.
if the user types something within the second, the timer is beeing resetted
and it starts from beginning waiting another second for the user being idle.
Hope you like it :-)
Thomas

You are confused; but this is your normal state.
