what is the %u option in menu?

[r5r4y]

just from curiosity...
i see many programs use this, for example:

totem %u

what is this option do?

[Tibuda]

When you right-click a file and choose the "Open with another application" option, I think it replaces the %u with the file name. Not sure about it.

Possibly, because I opened totem with that option, it was looking for a file, that did not exist.

Here you go.
u means url, f = file, d = directory, capitals means mulptiple of those. See the link for more.
