Controlling the UI and the hotkey toolbar

[tromboneandrew]

Is there someplace where I can see listed all the things I can do with the hotkey toolbar, and suggestions for the setup aside from the default? As characters accumulate more and more skills and useable items, organizing this really becomes important and it is a weak side of my generally weak ToME skillz.

I know so far:

How to unlock the layout so I can resize and move it (and the chat/text windows) with the little drag icon on the lower right of each box.
How to change the size of the icons in the toolbar, so I can customize how many rows/columns go in based on the combo of the box size/shape and each icon's size.
How to mouse-drag the icons around, plus using 'm' to go to that menu which includes the auto-use options.

I have not figured out:

How to mouse-click the drag icon if it's hidden behind something, like the tiny sub-menu that is on the lower right of the entire screen.
How to resize the display itself or otherwise get the character to be centered in the visible part of the map, not the map before the toolbar overlay.
A convenient way to organize the toolbar and hotkeys so I don't end up making 3-4+ major reshufflings throughout the game as my character progresses (and doesn't die).
How to get a useful object that I nevertheless have to swap out once in a while (like wands/totems) always map to a particular spot when I swap it into inventory slots.
Other tips and tricks that people generally set up to make things easier.
