Setting keybinding for org-support-shift-select t

Setting keybinding for org-support-shift-select t

[Christopher Dimech]

How can I construct a keybinding to set

org-support-shift-select t

Also how do I turn off org-support-shift-select in my .el file?

See the docstring,

   C-h v org-support-shift-select RET

it says "The default of this variable is nil".
But you can set it to whatever like this:

  (setq org-support-shift-select 'always)

Don't forget to byte-compile your init file(s)...

Got it, thank you.

A related job is how to disable org-support-shift-select
using a keybinding operation.

Well, here's a "straight"forward way do it:

(require 'org)
(define-key org-mode-map "\M-]"
  (lambda ()
    (interactive)
    (let ((vals (list nil t 'always)))
      (nconc vals vals)
      (setq org-support-shift-select
            (cadr (member org-support-shift-select vals)) ))))

(defun function-name ()

  )

(require 'some-mode)

(define-key some-mode-map "[\MODIFIER-]key[-...]" #'function-name)

E.g., it can look like this:

(require 'org)

(define-key org-mode-map "\C-c\C-c" #'org-latex-export-to-pdf)

Re: Setting keybinding for org-support-shift-select t

[Christopher Dimech]

A problem I am encountering with keybindings is that I end up with very strange
key combinations. I rather type a key followed by a string as is done in Emacs
such as "M-x org-mode". Is there an relatively easy way to do this for one's own
operations?

The same way Emacs does it:  define your function as interactive, e.g.:

    (defun scroll-up-1-line () "Scroll up one line."
      (interactive) (scroll-up 1))

interactive can handle functions that take parameters, too, and will
prompt you when you execute the function with M-x.  It can also
interpret C-u and other numeric prefixes.

Well, you don't end up with anything, really, not
this early on at least, just pick key combinations
that makes sense to you... redefine or remove them,
if you later on don't like 'em.

First check with C-h k KEY that they don't do
anything useful already...

They have to be interactive (or "commands"), that's
all

(defun my-best-command-yet ()
  (interactive)
  ;; do whatever you want
  )

M-x my-best-command-yet RET

We should compare notes!

(defun scroll-up-1 ()
  (interactive)
  (scroll-down 1) )

... or maybe it is less fun that way?

Let's try to do a simple thing

I have (global-set-key (kbd "<f1> a") 'org-agenda)

How can I use "<f1> agenda" to fire org-agenda.

That's great, but if I want to fire my own function, I have used
the following to bind it to "<f2> q". But what if I want to use
"<f2> myagendaa" to fire the function myagenda

( defun myagendaa ()
    (interactive)
    (org-agenda)
)

(global-set-key (kbd "<f1> q") 'myagenda)

Re: Setting keybinding for org-support-shift-select t

[Christopher Dimech]

The following gives me problems if I have keybindings associated
with <f1> such as "<f1> q" to display agenda

(global-set-key [f1] #'execute-extended-command)


Next is my code


( defun myagendaa ()
    (interactive)
    (org-agenda)
)

(global-set-key (kbd "<f1> q") 'myagendaa)

(defalias 'agenda #'myagenda)
(global-set-key [f1] #'execute-extended-command)

When I hit <f1>, it is showing as though I hit <M-x>

It's not clear to me what you're asking/saying.

But yes, if `f1' is defined as a prefix key, and
you then instead bind it to a command (and not
to a keymap), then it's no longer a prefix key.

It either is or isn't a prefix key.  If bound to
`execute-extended-command' then it's not, so
`f1 q' won't work - as soon as you hit `f1' the
command `execute-extended-command' is invoked.

If bound to a prefix key, when you hit `f1' Emacs
waits for you to hit one or more additional keys,
to complete the key sequence.

Re: RE: Setting keybinding for org-support-shift-select t

[Christopher Dimech]

I have usually used key bindings to do some operations I like. But then,
the keybindings became too cryptic for me to remember and thought of
using my user defined function names for the more complicated operations.

As you are saying, I can either have <f1> defined as a Prefix-Key
or use it to call my user defined functions.  Hover I cannot use <f1>
to do both - calling functions and using keybindings.

So then I might have, for example, <f1> to use with keybindings and
<f2> to use with my user defined functions.

Correct me if I am wrong, but I think I understood you.

Yes, I believe you understood.

A key can _either_ be bound to a keymap (and to
a prefix command, which is, in effect, just that
keymap) _or_ be bound to a command (which is not
a prefix command, i.e., not just a keymap).

Removing the parenthetical qualifications: A key
can either be bound to a keymap or to a command,
not to both.

Either Emacs sees only a prefix key and waits for
the rest of a key sequence or Emacs sees a completed
sequence and invokes its command.

Re: RE: RE: Setting keybinding for org-support-shift-select t

[Christopher Dimech]

Instead of using

(global-set-key [f2] #'execute-extended-command)

can I call my function directly,

(global-set-key "[f2] fnm" #'myfunction)

You invoke all interactive functions (commands) the
same way, it doesn't matter if it is your own or
anyone else's.

You can assign them to a keystroke (best for stuff
that is commonly used), and then choose any key or
key combination you'd like (see previous posts).

If you don't want to do that, but instead type the
entire function name, you can do

M-x function-name RET

M-: (function-name [ARGS]) RET

or type (function-name [ARGS]) and evaluate, as in

(forward-char 1)
                ^ evaluate me

You can also use aliases to type whatever you want
instead of the proper name.

Do you want to type it, use M-x function-name RET.
You don't need to do anything extra, just write the
interactive function and evaluate it.

If you instead want to assign it to some key, well...
do it!

Not with that KEY argument to `global-set-key'.

You can bind your function to a legitimate KEY value.

(global-set-key (kbd "<f2> x") 'myfunction)

You need to read up on key bindings.  Start with
`C-h r key bindings', which takes you here, but
in Emacs:

??? are you for real?

If you want to bind a shortcut to a command, then
yes, something like this is enough:

(require 'org-agenda)

(defun agenda ()
  (interactive)
  (org-agenda) )

(global-set-key [f1 ?q] #'agenda)

Re: Setting keybinding for org-support-shift-select t

[Christopher Dimech]

Not a troll, but looking hard on various ways to do things, which would
then be useful for other when I release the code.

My idea is this:

Call the operation using the function name using "<f2> func-name".
But this is the same as doing "M-x func-name".

However, can I use the <f1> prefix before the function name
just to show just my functions, not all of them.

Well then, it is one of many improvements you can
make to your code :)

The symbol's name should already tell you it is
intended to be used as a function (the function of the
symbol should be used). But for extra clarity, add
the sharp quote.

Also if you byte compile the code, which is
recommended for Elisp perfecting purposes, debugging,
and execution speed, _if_ you byte compile the code
the byte compiler will tell you if the function isn't
known to be defined... there was a thread about this
(WRT lambdas) recently, check it out if you can find
it (don't remember the subject TBH, I think we
hijacked another thread so probably won't even be in
the subject now that I say it...)
