shortcuts suddenly changed

[yairMSKTU]

i saw other asked the quesion but it didnt solve my problem.

i have autocad 2019.   

few days ago my shortcuts changed.   up until then 'x' was explode,  't' was trim.  now 'x' is xopen and 't' is torient.

few days ago some updates poped up and i clicked it so maybe that did something ?   all i do know is the the .pgp files, according to windows, was modified years ago.

how to solve the issue and go back to the shortcuts ive been using for the last few years ?

If you don't want to do the System Restore then edit your Acad.pgp

Use Express Tools, and edit the alias

or open the Acad.pgp with text editor and fix it.

If you edited the Acad.pgp file and still had the same issue use the Express Tool instead. Besides being simpler to use if you have multiple Acad.pgp files saved in your Support folders it always modifies the one that's being loaded by AutoCAD and if there's duplicate definitions of a shortcut it modifies the correct (last) one making it foolproof!

@yairMSKTU Looks like your AutOCAC2019 session found a different PGP file to use: the program always uses first found. "now 'x' is xopen and 't' is torient" is a very custom and personal choice, not an AutoCAD default.

Did you change folder placements in OPTIONS' FILES tab?
Someone else use your PC and AutoCAD?
what all did you change with your now old 2019 software or PC? Perhaps an add-on removed or added, new PC, new install where saving the old setup was forgotten, something. System Updates in Windows don't usually affect old installed AutoCAD2019 that specifically.
