%(x,y) Shortcut on [shift] + [9] menu

[compsystems]

Hello

I think it's important, a shortcut to the function %(x, y), x percent of y. In the [shift] + [9] menu there is enough space to place the [%] icon.

Another important shortcut in CAS mode is that the [shift] + [5] combination should show a pop-up box, that is with three options

1: [] for lists
2: set[] for sets
3: poly1[] for polynomials in vector form.

Also please add in the 2D templates the following operators
CEIL ⌈ ▣ ⌉ and FLOOR ⌊ ▣ ⌋ in notation exofix
