I have tried to configure lister (the external viewer of Total Commander) for use with WinSCP. And - it actually works. There is just one tiny last step missing. I have added a new user-defined command and assigned a shortcut (ctrl-0). Then I went to the registry and changed the entry to VK_F3 (0x72). Now "F3" appears in the menu. However nothing happens when I press F3. Something seems to eat up all function keys. Is there already a trick possible with the current release to get it to work?
WinSCP 5.5.2, GUI-Version, Win7
