There is no need to use (obscure) keyboard shortcuts at all, since the 
toolbar presents buttons for "back" and "forward" that should be easy to 
recognize -- there are also tooltips to explain them.

In fact, until some days ago I did not know about A-LEFT and A-RIGHT of 
major browsers (e.g. Firefox), but these keys were mentioned in the 
Navigator plugin documentation, and recommended for rebinding in jEdit.

I do check for jEdit keymap conflicts routinely, since this is not 
ESCAPE-META-ALT-CONTROL-SHIFT with an infinite space of possibilities. 
There is indeed an overlap with actions called shift-left ("Sift Indent 
Left") and shift-right ("Shift Indent Right"), but as far as I can tell 
they are the same as S-TAB and TAB (which I am routinely using for that).
