some common definition that we use throughout app. Do not add more, only what is common. I should not have added Sh-F9 and C-left since they are rare, but only to show they exist.

THESE are now obsolete since we are moving to string based return values else they should be updated.

#popupmenu(hash, config = {}, &block) ⇒ Object

this is a quick dirty menu/popup menu thing, hopnig to replace the complex menubar with something simpler. However, the cursor visually is confusing. since the display takes over the cursor visually. When we display on the right it looks as tho the right menu is active. When we actually move into it with RIGHT, it looks like the left on is active. OKAY, we temporarily fixed that by not opening it until you actually press RIGHT FIXME : there is the issue of when one level is destroyed then the main one has a blank. all need to be 

repainted.

FIXME : when diong a LEFT, cursor shows at last row of previous , we need a curpos or setrow for that lb
