CAD的快捷键全部不能用了。 急，请高手支招，急着用！

将以下代码复制到一个新建的文本文档，将此文件另存为acad.pgp文件，然后替换CAD中的acad.pgp文件或者复制到CAD的安装目录中问题就解决了。

; Command alias format:
; <Alias>,*<Full command name>
; The following are guidelines for creating new command aliases.
; 1. Try the first character of the command, then try the first two,
; then the first three.
; 2. Ignore "DD" at the beginning of a command.
; 3. Abbreviate the following prefixes:
; Examples: 3 for 3D, A for ASE, D for Dim, I for Image, R for render.
; 4. Once an alias is defined, add suffixes for related aliases:
; Examples: R for Redraw, RA for Redrawall, L for Line, LT for Linetype.
; 5. An alias should reduce a command by at least two characters.
; 6. Commands with a control key equivalent, status bar button, or function key
; do not require a command alias.
; Examples: Use Control-N, -O, -P, and -S for New, Open, Print, and Save
; 7. Use a hyphen to differentiate between command line and dialog box commands.
; 8. Exceptions to the rules include AA for Area, T for Mtext, X for Explode.
; Sample aliases for AutoCAD commands
; These examples include most frequently used commands.
