Mimic Windows Snap Hotkeys in Xfce
It’s quite simple. Open Settings → Window Manager → Keyboard. Then find the various “Tile window to the…” options. Finally, pick your desired keys.
You can’t make it function quite as smoothly as in Windows 10, but it certainly helps.
Of course you can also just drag the window against the side of the screen with the mouse. But sometimes the keyboard is faster.
