Reload .Xresources without restarting the xterm

This will reload the .Xresources:

xrdb ~/.Xresources

Source: Arch wiki

xterm will not reread resources just because you run xrdb. X applications only read resources when they are initializing.

Besides the menu entry (added in patch #122, 1999), one could use two other ways to change the metaSendsEscape resource:

• escape sequence, documented in XTerm Control Sequences

  CSI ? Pm h DEC Private Mode Set (DECSET). ... Ps = 1 0 3 6 -> Send ESC when Meta modifies a key. (This enables the metaSendsEscape resource).

• editres (but very cumbersome due to the large number of resources)
