xlogo app defaults only quit on q then Escape
In a default installation (on Ubuntu) the
xlogo utility quits if I put focus in the xlogo window and then press q and then Escape. It doesn't quit if I just press q, or if I just press Escape.
This seems like an unusual choice, and I think it probably wasn't deliberate. As far as I can see it happens because
app-defaults/XLogo contains the mapping
XLogo*baseTranslations: #override \ <Key>q,<Key>Escape: quit()
I think that was probably intended to map either q or Escape to the quit action, but in fact the comma operator in Xt translation tables describes concatenation, so this actually represents the two-key sequence consising of q followed by Escape.
I suggest that file ought to read
XLogo*baseTranslations: #override \ <Key>q: quit() \n\ <Key>Escape: quit()
