[standby] Toolstips display time

[Fonte Boa]

Not properly a bug, but wouldnt it be possible to user set the time duration the commands tooltips is displayed?
Here, they appear during about 5 seconds and disappear. Then i have to put the cursor again over the command to see the instructions for more 5 seconds.
Maybe an option in preferences. Or what about if they dont disappear until user point the cursor over another command?
