Edit Keys

EDITING KEYS

  These are defaults, which can be redefined.  Note that while

entering text on the command line, some of these control keys take on text editing functions instead (CTRL - A, E, and K, and DELETE), so you should clear the command line before trying to edit atoms.

ATOM REPLACEMENT

  CTRL-C    Replace picked atom with carbon   (C)
  CTRL-N    Replace picked atom with nitrogen (N)
  CTRL-O    Replace picked atom with oxygen   (O)
  CTRL-S    Replace picked atom with sulpher  (S)
  CTRL-G    Replace picked atom with hydrogen (H)
  CTRL-F    Replace picked atom with fluorene (F)
  CTRL-L    Replace picked atom with chlorine (Cl)
  CTRL-B    Replace picked atom with bromine  (Br)
  CTRL-I    Replace picked atom with iodine   (I)

ATOM MODIFICATION

   CTRL-J    Set charge on picked atom to -1
  CTRL-K    Set charge on picked atom to +1
  CTRL-D    Remove atom or bond (DELETE works too).
  CTRL-Y    Add a hydrogen to the current atom
  CTRL-R    Adjust hydrogens on atom/bond to match valence.
  CTRL-E    Inverts the picked stereo center, but you must first
            indicate the constant portions with the (lb) and (rb)
            selections.

  CTRL-T    Connect atoms in the (lb) and (rb) selections.
  CTRL-W    Cycle the bond valence on the picked bond.

UNDO and REDO of conformational changes (not atom changes!)

  CTRL-Z    undo the previous conformational change.
            (you can not currently undo atom modifications).
  CTRL-A    redo the previous conformational change.
