HOW TO - Select bones in weight paint mode

Hello,
Im using maya presets, but im willing to change hotkeys but i dont know which ones to change…
with blender settings everything works well but maya left-click is weight painting and right-click is giving me some menu… i want to change this menu to bone selection, but there are like 1000000 blender hotkeys so i dont know which one to change…
Can someone help me please?
