In the 90's I had this vision that the menu and the scrollbar should be physically separated from the screen.

If you have (next to your monitor on the left side) a narrow physical display with menu entries in it. You get 4 things for "free", the user will expect there to be menu entries, the developer will understand the expectations to have menu entries, there is limited room to go nuts with the layout or shape of the menu and last but most funny, you won't feel part of the screen has been taken away from you.

The physical scrollbar should be a transparent tube with a ball (or ideally a bubble) floating in it.

Usage could be moving the pointer out of the screen. The scrollbar led goes on and you can hold the button to move the page. When using the menu the pointer [also] vanishes and the menu entry at that height is highlighted. (much better usability) Moving the mouse up or down highlights the above or below entries, if there are a lot of entries it may also scroll. It may be a touch screen but the most usuable would be a vertical row of 5 extra wide (3 fingers) keyboard buttons on the left with the top 4 corresponding to the 1st, 2nd, 3rd, 4th menu entry and the 5th one for page down. (scrolling down 4 entries) Ideally these get some kind of texturing so that one can feel which button one is touching.

This way knowledge in the world can smoothly migrate to knowledge in the head until eventually you can smash out combinations of M keys in fractions of a second without looking at the screen or the keyboard. The menu displayed is always in focus, you don't have to examine the view port to use it. Having a row of horizontal F keys is a design fiasco. Instinctively bashing the full row of those might come natural after learning to type, then learning to type numbers, then symbols and only if you frequently use applications that have useful F key functionality. I only really know F5 and F11 but I cant smash them blindly as I pretty much never use them. I just tried F1 in firefox and no help documentation showed up... I think that was what it was suppose to do? Not even sure anymore.

Having the antenna menu (file, edit, etc) at the top of the viewport is also ugly. For example, smashing the second then the top M key could easily become second nature. CTRL+Z is fine of course but it aint knowledge in the world. Does anyone actually use ALT+E+U for undo? Try it on the CTRL+F input area. It's just funny. Type something in the address bar then compare ALT+E+U with using the Edit menu.

A separate display would take many of these "design" privileges away from the clowns.

(note: I think it is ALT+E+U as the Dutch layout is forced on me by windos. Edit is called Bewerken and the shortcut is ALT+W!?! ALT+E does nothing.)
