Here the few steps to change the command shortcuts
in Autocad :
1. Go to the Manage tab in ribbon.
2. In the Customization section, select Edit Aliases or use command“AI_EDITCUSTFILE”,
write “acad.pgp” / “acadlt.pgp” and press enter.
3. Drop down list will open up. Tap Edit Aliases button.
This should open up your acad.pgp / acadlt.pgp file in a text
editor which by default in most cases is Notepad:
4. Scroll down the text editor and you’ll see a complete list of existing
commands with their default keyboard shortcuts in it.
5. Exp - Copy Command as this command is more frequently used, the default keyboard
shortcut for copy command is CO , it is two keys, to short it to
one key let’s change it to C. But C key is alreay assigned to circle
command.So Autocad will not change the short cut.
As circle command is less used than copy command, so we can change the short
cut key of circle command from C to CI which are the first two initials
of circle command.
6. Now you can assign the C key to COPY.
7.Now our shortcut keys are changed. To make it effective in the Autocad, you have
to reopen the Autocad.
8. When you reopen the Autocad file, you can see the command has changed.
If you want to add a new shortcut in the command list : -
1. For exp – Layer isolate command which helps in hiding or
isolating the objects in the same
layer.But the default shortcut for this command is too long which is LAYISO.
But this command is also frequently used when we are working with
multiple layers in the project, So to shorten that, we can add a new shortcut,
let’s say 1 in the command list at the last of all the commands.
NOTE : -
* Type the shortcuts in the same way other shortcuts are..Otherwise , it
will not accepted in Autocad command list.
* After adding, removing, and customizing a shortcut in command
list.Don’t forget to save the changes in the NOTEPAD.
* And also close the Autocad and reopen so that the changes may get
applied
So this is how you Add, remove, customize the keyboard shortcuts in the
Autocad.
