Simplified Keymap

This is a proposal to simplify some of Blender basic shortcuts, most of them are frequently used, so I think would be nicer if those hotkeys were done just using just one key.

I found that there is some keys that there isn't other functions applied to it and still the shortcut it's a combination of two keys.

Like Join for example, as far as I know the J alone doesn't have any function applied to it, so why don't just use only J as shortcut, instead of CTRL + J ? And is this case why not use Alt+J to Unjoin parts to be more consistent with other Blender's shortcuts.

So here is a list of shortcuts that I think could be simplified, please make your suggestions and help to check if there is any functions applied to the keys in any Editor Type in Blender.
   

• Join = J
• Unjoin = Alt +J
• Parent = P
• Clear Parent = Alt + P
• Make Links = L
• Clear Links = Alt + L
• Select More = +
• Select Less = -
• Views Pie Menu = V
• Set Vertex Colors = K
• Set Weight = K
