Change the font size of the "Parameter Info" pop-up?
Answered
The font size of auto-completion seems to change as that of the editor font size, but the "Parameter info" (in the screenshot below, the pop-up that shows lots of `indexOf`) does not, and the font is too small to read comfortably. How can I change the font size of that?

It can be changed only with the Settings (Preferences on macOS) | Appearance & Behavior | Appearance | Use custom font font. Please feel free to vote for related request: https://youtrack.jetbrains.com/issue/IDEA-230026
On similar pop interface, I can click on the three vertical dots on the right lower corner and change font size there.
