KeePassX is a password safe application. It manages login data and auto-inserts it the currently active form field when a specific key combination is pressed.
In the KeePassX application, the key combination Ctrl+Alt+A is not accepted. (Other key combinations like Ctrl+Alt+Q do work.)
By saying not accepted I mean, that the keys I press are shown in the corresponding form field, but as soon as I release them, the field gets empty again. Other key combinations, like Ctrl+Alt+Q, simply stay entered so I can apply the setting by pressing the Apply button.
Google told me, that in KDE Ctrl+Alt+A is usually used to trigger Activate Window Demanding Attention. Hence, I suppose (i.e. not know) that this might be the reason that this exact key combination does not work.
How do I release that key combination so I can use it for KeePassX?
I'm using Kubuntu 16.10 with KDE Plasma 5.7.5.
