Holding Super+R / Super+Shift+R allows resizing a window, with an arrow indicating in which direction a window can be resized. Resizing is done with the arrow keys or vim movement keys (h/j/k/l). However, pressing k does not resize a window upwards, neither when holding Super+R nor Super+Shift+R. It is the only vim movement key for which resizing does not work.
