Setting shortcuts for Properties window in Blender 2.5x
I had to fiddle a bit to find those, but it's actually easy: You must:
1) create a new shortcut in User Preferences -> Input -> Property Editor 2) set a F5 shortcut with action "wm.context_set_enum" 3) set a "space_data.context" attribute with valeu "MATERIAL"
You can set shortcuts for the following contexts: 'SCENE', 'RENDER', 'WORLD', 'OBJECT', 'CONSTRAINT', 'MODIFIER', 'DATA', 'BONE', 'BONE_CONSTRAINT', 'MATERIAL', 'TEXTURE', 'PARTICLE' and 'PHYSICS'
