Total Commander

Currently the F4 key is finally added to Lister, this is known from Help and history but is not visible directly in UI. It would be easier to discover this option if the edit by F4 is added to the Lister's Edit menu. Also, this menu item should be available only for supported document types and not available (inactive) for currently unsupported files like images, multimedia etc. Some additional explanations may be added to Help as well (optionally).

This requires translation so It will not be added until the next major release - se: viewtopic.php?p=448118#p448118

Sorry, I missed that post in discussion. Anyway, as Christian knows of this problem, it will be implemented soon or later.
