Hi Tanya,
Do they look like in the article, and do they disappear when you don't show
the formatting characters (say by clicking on the ¶ button)?
Then they're definitely tabs.
They can be deleted just the same as other text (Backspace key, Delete key).
Or you could use "Find/Replace": You can find tabs under "Special" (or type
^t into "Find what"), and replace them with nothing (just leave "Replace
with" empty).
Tabs can be inserted by pressing the tab key (on the left side of the
keyboard, above the Shift and CapsLock keys).
Or if you didn't insert them on purpose, it might have been "Click & Type":
If you double-click somewhere in the document with the left mouse button,
Word will insert empty lines and tabs so that the text you type next appears
where you clicked.
I turn "click and type" off (...in Word's menu, Tools, Options, Edit tab, on
the bottom -- in Word2003), because I don't like to have empty paragraphs
and tabs in my document.
If the arrows don't look at all like in the article, maybe you can describe
them in more detail?
Regards,
Klaus
