Invite player in group/send whisper message to player at reticle by help of keybinds

[Baertram]

Hey there,

would it be possible to invite a player that you just looked at (reticle is aboe the player, or was above the player and one remembred the last name below the reticle somehow) into a group, or send a whisper message, by just pressing 1 key?

I personally don't like this wheel, where I need to press the key and move the mouse. It often is too complicated :-(

Thanks for your feedback.
