I've found this article about using the shift key to make the tooltips popup when you want them to. This works ok, but I was wondering if there is a way to just add a delay to the tooltip. I like the default hover behavior, it's just a bit too eager on the display. I'm using Helios on Windows.

Excellent question!
There doesn't appear to be a control in Eclipse to do it, but these two blog entries:
- http://untamedmind.wordpress.com/2008/11/08/changing-the-mousehovertime-add-delay-on-the-tooltips-pop-up/
- http://dandar3.blogspot.com/2008/09/tooltip-delay-in-windows.html
both say it can be done in the windows registry. Caveat: I have not tried this.

Thanks. Guess I was just googling it wrong. I already had TweakUI installed (from the second link). Never even thought to look there. – xecaps12 Apr 27 '11 at 19:35

2Any user feedback for Eclipse on GNU/Linux? – donfede Mar 03 '13 at 21:07

32nd option worked for me, used `MouseHoverTime` of 500 on Windows 8.1. Seems like Eclipse really should have a separate setting for this, though. – AlainD Nov 23 '16 at 14:31
Eclipse tooltip delay is derived from Windows, so if you change the delay of windows by editing registory it will show delay on eclipse as well.
In Windows -> Start -> Run -> regedit.exe
Go to below path in registry.
HKEY_CURRENT_USER/Control Panel/Mouse/
Modify value for Key MouseHoverTime
MouseHoverTime : 600
NOTE : The value is in miliseconds, for me it was 8 miliseoncds and I changed it to 600 miliseoncds.
System restart required after changing value in registry
OR
You can also assign shortcut key to get the tooltop when ever you want. Please refer below link

I suggest to turn off hovers by default, and define a customKey in Eclipse->Preferences if necessary.
