Patch for #4133 deleting an expanded directory in VFSBrowser results in IO error dialog
emacs2.patch is a corrected version that makes an additional needed change to Emacs_Next_Line.bsh.

Patch for #4140 jEdit 5.7: bundled Emacs Macros are broken
I'm using Linux too (Arch Linux with i3 for a window manager). At first I thought i3 was intercepting these keystrokes but I tried running a different window manager, and it still didn't work. Maybe a full desktop environment such as GNOME would define these shortcuts for all applications, and I'm having problems because I'm using lightweight window managers.
