Directory Dialog (Unix)

The Directory dialog allows the selection of a directory.

The Directory Name field expands shell metacharacters like

'~' and $variables . You can enter a directory by either pressing <Return> or the Open button.
Entering a C-shell regular expression in the Filter field and pressing the Update button filters the list to only those entries that match the filter.
Directories menu
The Directories menu lists the most recent active directories. Choosing an entry from the list opens that directory and displays its contents in the Directory List.
To remove entries, choose Options > Edit Directories.

Options menu
The Options menu lets you configure entries for the Directories menu, create directories, and select whether hidden files are displayed.

Directory drop-down
The Directory drop-down shows the list of directories in the path from the current directory to the root. You can click on any directory in the path to enter it.
Buttons
