This choice of symbols is strange, because all of those keys can be easily accessed using your right
hand on the Alt key, and the left hand on any of those symbols (they are available on the left half
of the keyboard). What is obstructed by the right hand though is the numbers. This is what the
symbol bar should contain.
symbol bar should contain, and it should look like this:
Additionally, it should contain some symbols that are unavailable on the physical keyboard. That is
the symbols "$", "%", "&", "=". However, as those are not used as often as numbers, they should be
hidden away in a collapsed menu along with more, less frequently used symbols.
(1) (2) (3) (4) (5) (6) (7) (8) (9) (0)
When pressing the shift key, the number bar should change into a symbol bar. This will contain all
the symbols not found on the physical keyboard. It'll look like this (likely the most needed symbols
are in the middle):
(^) (\) (|) (=) (%) (&) ($) (<) (>) (MORE)
When pressing more, additional less-used symbols will be shown.
