For v.1.1.0 when a file is highlighted in pcmanfm and the user press the "alternate menu" button (the one on the right side of the space bar next to Ctl key), the menu that appears only lists the default options, as if nothing were highlighted. This function doesn't even work on a PCManFM window or the Desktop.

Trying it in a virtualized Lubuntu 13.10 with PCManFM installed from Git repository, there's a partial solution: we can use the mentioned feature pressing Shift+AlternateMenu ONLY in PCManFM windows, not in Desktop.
