[shmem]: ctags is a program which (recursively) extracts the symbols from source and stores them in a one-file database. This allows you to query the locations where these symbols (e.g. a subroutine name) are used anywhere in the source code tree...
[shmem]: ...from inside the editor.
[shmem]: apt-get install exuberant-ctags
[Lady_Aleena]: I think I heard vim has a big learning curve.
[shmem]: then in the root of your source tree run: ctags -R
[shmem]: you get a file named tags where all symbols and the places where they are used are listed
[Lady_Aleena]: geany may not support that.
[shmem]: I see that there is a plugin geany-plugin- codenav
[shmem]: maybe that supports ctags, check the documentation
