CTRL+Z to restore original "save as" file name

[HT-7]

Accidentally pressing a key after the "save as" dialogue or clicking on an existing file appears causes the pre-filled file name to be lost. The dialogue needs to be opened again to get back the pre-filled file name. For example, a file needs to be downloaded again.

Please add support for CTRL+Z to restore the original file name or a button for "restore original file name".

The file save and open dialogs are provided by the toolkit the application is written in. Mint does not develop nor have control over these.
