Under Eclipse I can inspect expressions/variables in debug mode with Ctrl+Shift+I. In IntelliJ IDEA (Community Edition), I can add expressions/variables to the watches, but on the next debug they are lost.
Is there any way to inspect variables and expression on the fly when I'm debugging?
Quick evaluate expression
with Ctrl + Alt + F8 (or on a Mac: Cmd + Opt + F8) gives me exactly what I want.
Do you mean "Evaluate expression" action Alt + F8?
Many more useful shortcuts are in Intellij Reference Card.
Ctrl + Alt + F8 will work.
This shortcut may trigger the Intel HD Graphics hotkey for resetting display settings.
Alt + Left Mouse Key
will also work.
If you want to view/edit the shortcuts, you can go to Settings
(Ctrl + Alt + S) -> Keymap
and search for Quick Evaluate Expression
Ctrl + Alt + 8 in case of Intellij Idea 2019.2 and Ubuntu 18.04.
In mac, alt+clicking variables help !
