Texstudio has a handy feature that is popup a list of known labels or bibids when you \cite or \ref. For example:

enter image description here

However, I found this tooltip is not that stable. Many times, it disappears when I am still typing for unknown reason or if you unfortunately click the mouse. like this enter image description here

The annoying thing is that if the tooltip disappears, it never popup again automatically. I found I have to delete \cite and retype start from \ to make tooltip appear again.

So I am wondering if there is a shortcut to popup the tooltip again after it disappear?

  • As far as I know there's no shortcut, you have to do exactly as you've done so far. Delete all \cite cmd and retype it. If it bugs you that much Report as a bug Commented Oct 10, 2016 at 8:32

  • Yes. To check, if it's working, you can also run it from the menu Idefix -> Complete -> Normal Commented Oct 10, 2016 at 16:29
  • Thank you. I understand why. My input has taken over ctrl+space
