Eclipse - Run/Debug shortcut key doesn't work

Question

In Eclipse I can only run/debug my project by using one of the menu buttons. Pressing F11 or Ctrl + F11 does nothing. I\'ve mapped Debug Las

Answer 1

The only solution works for me ;

Open Key mappings (CTRL+SHIFT+L twice) Find the debugging shorcuts (F5,F6,F7...) and select

then change the When action value from "Debugging" to "In Window"

Answer 2

Edit: My post doesn't directly react the original malfunctioning-F11-behavoir question. But the issue I had seems quite similar and definitely it relates to some other (quite highly voted) answers.

I've bumped into a similar issue too when I upgraded to Eclipse 4.7 Oxygen and needed to install several plugins from a scratch. F* keys didn't work in the debug perspective even though the appropriate key bindings were configured correctly.

Unfortunately, neither reseting perspective nor reseting key bindings (as suggested in some comments here) helped.

The trick that fixed that for me was:

Preferences > Run/Debug > Perspectives > Restore Defaults

That revived the F* keys functionality in my debug perspective. I don't thing this is the universal way how to bring the behaviour back, but among the other "Resets to defaults" this one may be the right one in some cases, so it's worth trying.

Answer 3

If your computer has a fn lock/toggle that switches between fn and the f1-f12 keys, make sure that you didn't toggle the other mode by accident.

Answer 4

I battled with a new Dell laptop, so in case it saves someone time ....

By default, the F-key priority was set for sound, brightness and music, e.g. F9 brings up Windows search. --> This is without pressing the Fn key and the desired Fkey as expected.

To toggle the priority, look for Fn + Esc. That allows F5, F6 etc to work as expected. You can press Fn + F6 for skipping music tracks

Answer 5

Go to Window -> Preferences -> General -> Keys For each key that doesn't work: Set your binding to whatever you want. - I just copy the command then change "When" from "Debugging" to "Editing Java Source". good luck.

Answer 6

Try F11. It worked for me. Im using Eclipse in ADT.
