The first line represents the default directory of the speedbar frame.
Each directory segment is a button which jumps speedbar's default
directory to that directory. Buttons are activated by clicking `\\[speedbar-click]'.
In some situations using `\\[dframe-power-click]' is a `power click' which will
rescan cached items, or pop up new frames.
Each line starting with <+> represents a directory. Click on the <+>
to insert the directory listing into the current tree. Click on the
<-> to retract that list. Click on the directory name to go to that
directory as the default.
Each line starting with [+] is a file. If the variable
`speedbar-show-unknown-files' is t, the lines starting with [?] are
files which don't have imenu support, but are not expressly ignored.
Files are completely ignored if they match `speedbar-file-unshown-regexp'
which is generated from `completion-ignored-extensions'.
Files with a `*' character after their name are files checked out of a
version control system. (Currently only RCS is supported.) New
version control systems can be added by examining the documentation
for `speedbar-this-file-in-vc' and `speedbar-vc-check-dir-p'.
Files with a `#' or `!' character after them are source files that
have an object file associated with them. The `!' indicates that the
files is out of date. You can control what source/object associations
exist through the variable `speedbar-obj-alist'.
Click on the [+] to display a list of tags from that file. Click on
the [-] to retract the list. Click on the file name to edit the file
in the attached frame.
If you open tags, you might find a node starting with {+}, which is a
category of tags. Click the {+} to expand the category. Jump-able
tags start with >. Click the name of the tag to go to that position
in the selected file.
