I like my interactive functions to generally use the word or region at
point as a default. Is there a way to make the read-string mini buffer
input to pre-select the default value?
e.g
consider
(setq url (read-string (format "Url (%s) :" url) url nil url))
Here I would like to see at the input prompt
Url (xyz): xyz
with the default value of "xyz" already selected. In other words
the same behaviour as when you tab into a populated entry field in most
of applications.

Hi Kevin,
Sorry if I was not clear. I don't mean a default value - I mean
pre-selected as in "in region". e.g when you tab to a field in a web
form for example - The data in the field is highlighted/selected. I
already had a default value set as "url" in the code above.
e.g
goto www.Google.com
enter some text and tab to a button then tab back. The text in the
search field is selected.

Something like this ?
(defun minibuffer-select-inital-input ()
(let ((start (next-single-char-property-change 1 'read-only)))
(when (< start (point-max))
(set-mark start)
(setq mark-active t))))
(add-hook 'minibuffer-setup-hook 'minibuffer-select-inital-input)
(read-string "> " "Hallo")

Yes, thanks. But I released I was hoping for too much here since
region/mark etc works so many different ways depending on settings. As
"dim" in the #emacs said, probably best to rely on C-a C-k. e.g With my
setting hitting right arrow there results in "end of buffer" error.
Thanks for your time though!

1. I was going to suggest something like what ap said.
That seems to respond to your request, so I'm not sure what you meant above - in
particular about using the right arrow. If point is at the end of the input (end
of buffer), then why would you hit the right arrow? What would you like the
right arrow to do in that context?
2. [You won't like this related answer, but it might help someone else. ;-)]
In Icicles you can elect to always insert the default value as initial text. And
if you do that, you can also elect to automatically select it (as the active
region). And you can choose where to leave the cursor: before or after the
default text (whether or not you choose to auto-select it).
This means that if you use, say, Delete Selection mode, and you choose to
auto-select the default input, then you can just type other text to replace it,
or hit `C-d' or Backspace (DEL) to delete it.
And even if you choose not to auto-select the default text, you can use `M-k'
anytime to clear the minibuffer (easier than `C-a C-k').

The way I use the kbd, right arrow to remove select and edit existing
text with cursor at end or any other (non directional) key to clear the
field. Try Google example : enter text, tab to button, shit tab back,
press right arrow. But I see this is probably not a good idea to
enforce in emacs.

Hmm. I must be more careful when typing "shift" .... Sorry.
