I'm on Emacs key bindings, and when I want to change buffer I do C-X C-B (I think it is C-S-b in 'normal' key bindings). When using arrow keys to move to another buffer, the current line is only slightly highlighted. If selecting a line with the mouse, then the line becomes much more highlighted and if now moving by arrow keys the highlight color sticks. I'm using dark theme. I would like the brighter highlight color to be used even if only moving by arrow keys.
