Ctrl-T does not work!

[Steven Woody]

Hi,

I am using cscope to browe c sources in gvim.  According to the cscope manual, when I jump into a symbol, I could jump back by pressing 'Ctrl-T'.  But I always get "at bottom of tag stack". Could anyone here can here me how to check what's the cause of the issue?

Thanks.

"Ctrl-T" is mentioned in two places on the cscope help page,
if_cscope.txt. The first one has this note:

(Please note however, that you don't actually jump to a cscope
tag simply by doing Ctrl-] or :tag without remapping these
commands or setting an option. See the remaining sections on
how the cscope interface works and for suggested use.)

There are a number of ways to configure cscope in vim to get the
behavior you prefer, including being able to put the results into
the tag stack or a quickfix list, so I'd suggest reading all of
":help cscope" and configuring it the way you want.

Regards,
Gary

You need to use CTRL+] to jump to the definition of that symbol after
you have created the ctags file using ctags from the exuberant-ctags
package (on Debian). Then CTRL+T should bring you back to where you
were before. If you didn't do the jump in the first place, the
jump-back-stack will be empty and that's the message you would see.

Well, you can always use CTRL-O instead.

Thanks.  Both CTRL-O and 'set cscopetag' work!
