The definition key of cssag in Emacs is invalid.

The definition key of cssag in Emacs is invalid.

1. The cssag El plug-in is xcssag. El. Use "sudo find/-name xcs.pdf. El" to find the location of the file.

2. Open xcsloud. El
Find the "(define-key csbol: Map" \ c-CSS "'cscope-find-this-symbol)" modified statement
On my machine, the "\ c-CSS" definition method cannot accept key input, and is redefined as "\ c-c \ c-S \ c-s"
That is, the following statement: (define-key csbol: Map "\ c-c \ c-S \ c-s" 'cscope-find-this-symbol)
Modify the key combination defined in the same way ("\ c-CSS ")

3. Enter Emacs and test whether the definition key is successful.

Problem to be resolved
1. When defining keys, they cannot be case sensitive, resulting in overwriting.
For example
(Define-key csbol: Map "\ c-c \ c-S \ c-s" 'cscope-find-this-symbol) is overwritten by the following key binding
(Define-key cscope: Map "\ c-c \ c-S \ C-S" 'csbench-tell-user-about-directory)
