This is my 2 cents for locking and unlocking viewports within a second. Just make sure that your viewport layer "VP" is turned on. Once you place the following into your lisp routines and reload it with your AutoCAD, then you'll just type "VL" to lock your viewport or "VU" to unlock your viewport. (DEFUN C:VL () (COMMAND "-VPORTS" "L" "ON" "All" "") ) (DEFUN C:VU () (COMMAND "-VPORTS" "L" "OFF" "All" "") ) Anybody got anything else to share with us using mutliple command short cuts.
