CTRL + / does not toggle comments for LaTeX and Java

[proteusGIT]

Description
Even for the example, CTRL + / does not add line comments

Expected behavior
Adding and removing of // at beginning of line for java.
Adding and removing of % at end of line for LaTeX.

Actual behavior
Nothing.
I am on windows right now.

Apparently, the InputMap contains the key-combination and the ActionMap contains the corresponding action but the action is never executed.
The action is executed when associating e.g. the key-combination CTRL-K to it.
So maybe there is an issue with CTRL-/ as a key combination?

Hmm, it works for me. Is your keyboard QWERTY or a different layout? We've had issues with non-US users having issues in the past around this keystroke, which is why it's disabled OOTB for Linux
