@himew hello
You have several possibilities :
you connect a real keyboard and mouse (for all former computers, you should get a mouse/keyboard combo, it's quite usefull. Bluetooth ones work fine).
or you edit a pad to keyboard file (.p2k file) where you can assign mouse button or keys to a button on your pad.
See this doc :
