#121 Filename renaming - cursor action

[Lyndon Hill]

When I rename a file the characters up to the first dot are highlighted.

Currently, if you want to add something at the start of the text you must press right arrow, left arrow to clear the highlight and place the cursor at the start of the test. This does not seem logical.

When I press left arrow I want the cursor to move to the start of the highlight and clear the highlight. When I press right arrow I want the cursor to go to the end of the highlight and clear the highlight.

I think this is more natural behaviour.
