I've just had a look through Help and the shortcut keys and I see what you mean by F10 and looping (it's not something I use).

As far as I know, BIAB does not allow mapping of keys. This is done at the programming level

With the above in mind, it sounds like you'd be better off using the "Loop section" dialogue window that I've highlighted on the graphic below.

If your BIAB view is different from mine, use CTRL+T to change views.
