How to view only certain file types?

I´d like to have a filter, for example, that shows only .wav & .ape files. I know, the filter field can do this, but i use that filter in "automatic" mode, which is cool for the average usage.

But sometimes it would be handy, if possible, to use a hotkey, that hides all non matching file types & all folders. Another related thing is, when i started to use Opus i had that filter field, that could show related file groups like music, images etc., but i wasn´t able to find that function. What´s the name of that filter?

Just something like this (hides all non matching file types & all folders):

Set SHOWFILTERFILENAME *(wav|ape) Set HIDEFILTERFOLDERS *

Yeah, that´s exactly it! Thank you!

Now i set up different shortcuts for file groups (text, movies, music..), which works well so far. I can apply the filter & by using the shortcut a second time, toggle back to the normal view, except that the folders remain hidden. I´ve tried Set SHOWFILTERFOLDERS * from the CLI, but for some reason the folders won´t show up.

Is there a way to handle identical shortcuts like using the "toggle" mode, like it would be possible using LMB & RMB? So, for example, if i press Win-1, it shows all images (filtering), then hitting Win-1 again toggles back to view the standard contents.

Did you add Set HIDEFILTERFOLDERS * to all your shortcuts? When I try the code I posted above, it toggles matching file types and all folders (they don't remain hidden here)?

Christiaan, you were right, in the process of having made 8 file type buttons i forget parts of your original button in some of the shortcuts.
