This keyword adds a window with a file browser. Set the 'MultipleSelections' flag to 'Yes' if the user is allowed to select more than one list entry and to 'No' otherwise. The Filename keyword specifies a wildcard with the initial path. Use forward slashes also under Windows.

The jth selected filename in the ith selection menu can be accessed by the Python plugin as yasara.selection[i].filename[j] (see below).

MainMenu: File
  PullDownMenu: Load
    PopUpMenu after PDB file: _N_MR ensemble
      FileSelectionMenu: Select a PDB file containing an NMR ensemble
        MultipleSelections: No
        Filename: pdb/*.pdb
      Request: LoadEnsemble
