Pressure	If your tablet supports pressure sensitivity, it will control the intensity with which the current operation is applied, relative to the intensity selected with the slider. In other words, if the slider is set to 50%, full pressure will result in 50% intensity, if it is set to 100%, full pressure will result in full intensity.
Pen buttons	The first and second pen buttons will increase or decrease the brush size.

For Ctrl and Alt, read ⌘ and ⌥ on Macs.
