keystroke for help

[baptiste auguie-5]

Dear all,

Yet again a silly question: how do you obtain help for a given function
(selected, or simply where the cursor currently sits)? I could use C-c C-v
but this requires me to type the word again. Also, is there a way to open
the help in a new window as opposed to masking the buffer I was working on?
I keep having to switch back to this one with the mouse and it's annoying
(e.g. when I start the R process it covers the file i was working with).


Many thanks,

baptiste

If point (emacs' term for the cursor) is currently on a R function,
 e.g. apply, then when you do C-c C-v you should see in the echo area:

Help on (default apply):

so if you hit return, the default is used.

See variable ess-help-own-frame if you want it in a separate frame.

Thanks! I'd tried that but sadly it was on a Grid function, and it so
happens that Grid isn't part of the default help system... I guess custom
packages can be added to the search path, somehow?

Best regards,

??
Of course, help is only searched in active packages, not in all
the thousands of packages that may be installed.

"cover"  ???
You should have the help open in another emacs buffer (in the
same frame aka "window"), and you can very quickly switch and
from that , using  C-x o / C-x 1 / C-x 0 / C-x b  etc etc.
*NO* need for the mouse here. There's nothing faster than the
keyboard.

Yes, but that will be even "slower" and more "mouse using".

OK, I think I'm getting somewhere thanks to the advice I've received.
Now if only they sold a microchip implant to store all these emacs
shortcuts, that you could plug in at your fingertips. I wonder what
programming language they'd use to control it.

Many thanks,

baptiste

If you're already in a help buffer, your keystroke is 'h' and it will
default to the word at point.  If you're in the '*R*' buffer, you'll
need to go through the arduous sequence of C-c C-v.
