I have recently installed Manjaro Linux KDE Plasma (Plasma version 5.20) and I have been getting some troubles setting up more familiar shortcuts. For example, I’ve been trying to set Maximize window to Meta + Up, but it doesn’t work. When I changed in KWin Global Shortcut, I tried it off in the Konsole and instead of maximizing the window, it writes “A” to the Konsole. I then switched back to default values but something happened because I cannot maximize using the default shortcut for any window (Which is supposed to be Meta + W, according to the menu when I lef-click the top bar of any window). When I hit Meta + W in the Konsole (willing to maximize it), I get “sw” written to it instead.
I also had some hard time setting up the Meta key to open the application launcher, but gladly I managed to find out that I was supposed to assign the same shortcut to Alt + F1 (for some reason also unknown) and this worked just fine, I can now use Meta key to open the menu. However, I’m still stuck with the maximize shortcut. It’s been kind of dissappointing for me because I’ve tried XFCE and Gnome, and it is my first time on KDE. Almost switching it back to Gnome, but now I have got my whole development environment set, I don’t want to install another desktop environment. Can someone assist me on what might be happening with these shortcuts involving the Meta key? Thanks in advance.
