Devise my own "overall" keyboard usage scheme

[xparq]

Well, it's mostly an inherently impossible task, but... everyone must have some "optimal" (i.e. good enough) solution.

• super ergonomic (without hardcore mods like Dvorak or CTRL -> CAPS LOCK etc.; but compatible with touch typing and the typical "coder typing" mode, where the right hand mostly rests over the navig. block, not the letters!)
• logical (learnable; -> "extensible")
• intuitive (guessable)
• (somewhat) compatible -- to survive on default emacs instances!
• extensible (-> "logical")
• (somewhat) portable -- to other environments (editors / IDEs)
• creative, inventive (Ctrl is not as bad if you use instead of your pinky)
