-Return after the end of the process' output sends the text from the

-Return before end of process output copies the current line (except
- for the prompt) to the end of the buffer and sends it.
+\\[comint-send-input] after the end of the process' output sends the text from
+ the end of process to the end of the current line.
+\\[comint-send-input] before end of process output copies the current line minus the prompt to
+ the end of the buffer and sends it (\\[comint-copy-old-input] just copies the current line).
\\[send-invisible] reads a line of text without echoing it, and sends it to
the shell. This is useful for entering passwords. Or, add the function
`comint-watch-for-password-prompt' to `comint-output-filter-functions'.
If you want to make multiple shell buffers, rename the `*shell*' buffer
using \\[rename-buffer] or \\[rename-uniquely] and start a new shell.
+If you want to make shell buffers limited in length, add the function
+`comint-truncate-buffer' to `comint-output-filter-functions'.
+
If you accidentally suspend your process, use \\[comint-continue-subjob]
to continue it.
`cd', `pushd' and `popd' commands given to the shell are watched by Emacs to
keep this buffer's default directory the same as the shell's working directory.
+While directory tracking is enabled, the shell's working directory is displayed
+by \\[list-buffers] or \\[mouse-buffer-menu] in the `File' field.
\\[dirs] queries the shell and resyncs Emacs' idea of what the current
directory stack is.
\\[dirtrack-toggle] turns directory tracking on and off.
