Better keyboard support

Thanks for this great app, it works well for me.

One improvement I would like to request is that an action is immediately executed when I press enter.

So in the following screen, just allow me to select a task with arrow keys and then press enter to execute it, instead of having to hit tab twice to get to the ok button.

There is a "check" column im not sure about?

When I use the mouse to select something, it's selected immediately on mouse over, without clicking, so i have to mouse over the action i want, then move the mouse out of the window being careful not to mouse over any other action, and then move it back in onto the ok button... so that is a bit unexpected either, but as im mostly a keyboard user and not a mouse user that's all fine with me :)

by the way, i already solved this by using rofi to make this menu :)
