Hitting F2 after opening the Advanced Renamer doesn't put the cursor into the preview list anymore (no matter where the focus is). Checking Macro works, but any editing only affects the first file. The remaining files disappear from the view.
Not sure how useful that is with the field in the Rename dialog itself, so maybe we should block the edit control from handling F2 so the dialog can handle it instead.
Currently, F2 will activate the preview list if focus is on anything other than the new/old name fields or the presets list (where F2 renames the selected preset).
I hadn't noticed Ctrl+S. That's probably another one the dialog should override.
Most of those keys are really for inline rename and just a bonus in the Rename dialog (where you'd be more likely to do the same things in different ways, if at all) so having them override the dialog's keys probably doesn't make sense in general. Should be easy to reverse that.
