Keyboard shortcuts for items under "Edit" menu
You can call a menu item with type a key after displaying "Edit" menu. When you disable the meta key, "Alt-E a" calls "Select all".
Select *a*ll Clear *s*creen Clear *b*uffer
Or did you suggested about alt key combination, like "Alt+v"?
It would be nice to have keyboard shortcuts for some of the items under the Edit menu that today do not have shortcuts. These include "Select all", "Clear Screen", "CLear Buffer".
