Search for text

Search for text

[john maclean]

Hi guys,

Basic stuff  here. Sorry if this has been asked before:-
 - Can one search for text at the location of the point? If a point is
within word "foo" I'd like to C-s <something> so that I dont have to
enter that word when promted for a search term
- I'd like to be able to search for say ^[a-g] with regular
expressions. Can any one point me to the location of the info doc?
- Finally I'd like to have all matching terms stay highlighted a bit
longer. C-s does highlight terms, but as soon as I C-v to look down
the page it's gone.

`C-s C-w' if point is before "f", `M-b C-s C-w' if point is after "f".

The "Regexp Search" and "Regexps" nodes are under the "Search" node.

    C-u C-s ^[a-g]

Alternatively: `C-M-s' (then `C-s' for subsequent searches of the same
pattern).

BTW, if you don't mind venturing beyond vanilla Emacs, you might also like
to try the crazy searching available with Icicles. This tells the story,
with screenshots:

hrm, i think I'll stick to the vanilla emacs for a while until I know
what I can do with the basic. It's always tempting for me to want to
learn *everything*.
[off topic but related: I'm using Jed also and C-s C-w does not work]

many commands no point learning them all.

Yikes, that must be frustrating.  Try `C-h a'.

Well, that's just why the strategic set on the reference card is
helpful...

Please don't toppost: the reading order is top to bottom.

refcard.tex (and probably also refcard.ps) are in the etc directory of
your installed Emacs.
