When you click on the Help menu with any of the mouse buttons you will get the following menu items:
Selecting this item will take you to the Info page which is the online documentation browsing system. You can simply click on the highlighted items and "Info" will take you to the document providing information about that topic.
After you select this item, you will get a documentation on the major and minor modes which are enabled in the buffer you are working with. See Modes, for information on Modes.
After you select this item, you will see the following message in the echo area:
List symbols matching regexp:
If you type "mode" and hit RET, you will get a list of all the symbols (like functions and commands). You can now get documentation on any of the given symbols by "clicking" on any of the symbols (i.e. drag your mouse on the appropriate symbol and release the button). For example, if you "click" on the ’auto-fill-mode’ you will get the following message in the window at the bottom:
auto-fill-mode Function, Command: Toggle auto-fill mode. With arg, turn auto-fill mode on if and only if arg is positive. In auto-fill mode, inserting a space at a column beyond `fill-column' automatically breaks the line at a previous space. Variable: value = nil variable not documented
Selecting this item will prompt you for a string just like when you select Hyper Apropos.... After you give a string name, you will get a listing of all the functions and commands containing that string name with a very short description about what that command does.
After you select this item, you will be prompted for a string name in the echo area:
Apropos (regexp):
Now you can give any string name, for example "mode" and hit RET. You will get a listing of all the variables and commands containing that string i.e "mode" with a short description of its function.
Select this item and you will get a listing of all the keys and the commands that they execute. Depending on which Major mode your buffer is in, you will get a listing of the special keybindings for that particular buffer also. For example, if you are in "Texinfo" mode, part of your list will contain:
C-c C-c n texinfo-insert-@node
C-c C-c o texinfo-insert-@noindent
C-c C-c s texinfo-insert-@samp
C-c C-c t texinfo-insert-@table
C-c C-c v texinfo-insert-@var
C-c C-c x texinfo-insert-@example
C-c C-c { texinfo-insert-braces
These keybindings apply only to "Texinfo" mode. See Modes, for more information on various modes.
After you select this item, you will be see the following message in the echo area:
Describe Key:
After you type a command key sequence, full documentation of that command will be displayed. For example if you type C-g, you will see the following documentation for C-g:
keyboard-quit: Signal a `quit' condition.
This means that C-g will quit whatever command you gave earlier.
This menu item provides documentation for a function. After you select this item, it will prompt you for a function name in the echo area:
Describe function (default <some function name>):
If you hit RET without giving a function name, you will get documentation for that default function name, otherwise if you type a function name and hit RET, you will get documentation for the given function.
You can get documentation on any variable by selecting this menu item. It is similar to Describe Function and will prompt you for a variable name.
After you select this item you will be prompted for a Unix command for which you wish to see the man page. You will see the following message in the echo area:
Manual entry: (default <some name>)
Now you can type any command, for example type ‘who’ and press RET. You will get the man page for the Unix command ‘who’ which lists who is on the system.
