Microsoft word processor question (autodeletion)?

Question

Whenever im on microsoft word processor, and im trying to edit a sentence, everytime i press space, or type a letter that suppose to go before a sentence, what happens is that it automatically deletes the first letter of the sentence to make room.

example: he went to school today

If i wanted to change he to she, typing an s before he changes it to se, as it auto-deleted the h.
same would happen if i put a space right before the h.

so what do i do to turn off that autodelete function

Answer 1

You must have hit the [Insert] key (above the delete key) on your keyboard. When this function is on, it will type over the text instead of in front of the text. Simply hit the [Insert] key again to take it off.

Answer 2

you're in the overtype mode

press the insert key once to switch out of it

you should see OVR in the status bar when in overtype mode

Answer 3

i think u might have on overwrite mode.. to change this press ins key on u r keyboard..
thnx
