Regex expression

Regex expression

[bcochofel]

I'm trying to match the beginning of all lines that have tab|space
chars and I'm using this:

^[ \t]*

But [ \t]* doesn't match spaces or tabs, matchs spaces and letter t...
Am I missing something?

Depends on if you're typing in the regexp interactively or
coding a routine to be loaded.  In a file, you're above syntax
should work.
If you're responding to an interactive prompt then you don't
use \t syntax (nor do you need to double \\ when
you want to search for \).  Use C-q C-i or C-q C-TAB to insert an
actual tab character.

I'm using C-M-s with that syntax.

Try to input it as: ^   [   SPC  C-q TAB   ]

Please ignore my prior typeo C-q C-TAB
which has an erroneous C- in fron of TAB.

Thanks, that works...
I can change [ SPB ] to [ ], right?

Why not just TAB?

Habbit I suppose.
I can't always remember what's standard vs what I've customized.
C-q TAB works even if the TAB key is customized.
