change F2 to rename: yes,
because in many (Windows-)Applications F2 is used for that and Ctrl-R for refresh works fine (just like in IE, Mozilla, etc) After all, its configurable anyway, so who has used TC for a while would easily be able to rechange this option to Shift+F6.
I think an even better way would be an option to switch between two Option-presets, like mentioned before in this thread. So the classic preset will let TC behave like it is at the Moment (which is great, I think), and an "Explorer Mode" would change some Options to be more Windows-like. Personally, I change the following Options first when I install TC:
- Extensions displayed directly after filename
- Font Tahoma 8 plain
- File selecting like in Windows with left Mousebutton, right MB for Contextmenu
- Quick file search with just typing letters, not w ALT+Shift, I use this quicksearch much more often than the Command line
- Renaming Files using F2
I think these few options could let TC be easier to use for new users who are used to the windows interface, than with the NC-like behaviour. So I think two switchable Interface-modes could be a chance to reach more users with TC, because some users take only a few clicks to overview a new program and some of hem may reject TC just because some of their first tries did not deliver results in the expected way (just like F2, when the Source has not changed and the user sees nothing).
