In a program/script, a given function is implemented in many different areas of the code, e.g. declarations, GUI settings, subroutines, etc. So when you are working on this function you often need to jump backward and foreward from one area to another.
A "Jump Previous/Next editing point" would come handy.
Lines within say 5-7 lines should be considered the same "editing point". Only "long jumps" should count.
It seems that a short history, no more than 10 "editing points", should safice.
Yes, I know, I can set bookmarks and nevigate between them. But that would place me at the begining of an area, not were I was. Also, if I forgot to set a bookmark...
Identicaly to the IE browser and the Acrobat reader, the ALT->LEFT/RIGHT ARROW keyboard shortcut is recommended.
