Hi.
I have just bought Linux laptop from Tuxedo. It has KDE in it, that I love and used for few years.
But I’ve used Mint with Cinnamon and while theres a similar functionality with window tiling (Tux + arrow) that helps a lot, it also let me maximize OR tile to the top half of the screen.
Now in KDE it doesn’t seem to work. When I have the window tiled (or anywhere) and press Tux + Up it doesn’t maximize and it don’t work mixed with any other shortcut on the same keys.
Can the tiling work like this and I miss sth or KDE can’t do this?
Is there hope that the KDE will do that in future?
My laptop does that, if I press Meta+up (I think that is the same)
Plasma 6.4, Arch Linux.
Ok, lucky you. 
Ive been on Debian based (Kubuntu, Tuxedo OS).
It only tile the window to the top of screen, not maximize it on any of my laptops I’ve tried.
And if the window is at the top it doesn’t do anything.
It seems that I have misunderstood you. I thought you wanted the window tiled… But I think you can add a shortcut that maximizes the window (I have Meta+Scroll up set)
I also want(ed) this, because of my familiarity with the Windows OS windowing key bindings. I didn’t find out how to achieve it exactly, so I used the maximize binding Tux-PgUp.
Maximizing a window uses Tux+PageUp, not Tux+Up. Tux+Up tiles the window to the top of the screen (just like Tux+Down tiles the window to the bottom).
If you don’t like this, you’re welcome to change it in System Settings > Keyboard > Shortcuts > Window Management > Maximize Window
Yes, its possible but it’s not the point. But now both at the same time. Either you make it tile or maximize.
But it would be nice to either maximize if the window was tiled or tile it (make smaller) if maximized.
In Cinnamon it works nice.
How would it work for Tux+Up to do both things?
If the window is max => tile it to the top half
If the window is tiled/not max => max it
