How Can U Configure the Shape of the Highlight Window?

[Enoch]

Once I have opened the Highlight Window & shoved it off to the right, it appears coincidentally either as

 

1) a wide box with 2 columns,

like 4 colors on left (up & down) & side-by-side 4 colors on right (up & down) (thus I have 8 colors in 2 columns of 4 each);

or

2) a narrow box with 1 column,

8 colors up & down in 1 column.

 

However, I don't know what causes these box shapes. I prefer the 2nd variety, but don't know how to get it when I want it.

 

How Can I Configure the Shape of the Highlight Menu Window?

 

(BTW, it would be nice to dispense with the mouse/window process & use a keyboard shortcut to highlight colors by number. Going back & forth to that window takes time).
