A family of Microsoft word processing software products for creating web, email, and print documents.
Hmmm ...Yesterday I was working on the need to update my web page http://www.gmayor.com/AutotextList.htm I hadn't bothered for Word 2007, but as Word 2010 has the prompts I thought it might warrant another look.
The original entries h1 and h2 I felt were too short to be useful, so I created instead a pair of entries called heading1 and heading2.
Because of the number of matching characters you would expect the popup to occur when the 1 or 2 was completed, but the autocorrect activates when you type the 1 or the 2 to capitalise the word at the start of a sentence. This appears to inhibit the pop up. Thus when I type heading1 at the start of a new line the popup does not occur, but if I immediately type heading1 again it does.
This behaviour seems to be consistent, which gave rise to my sugegstion that the autocorrect was the issue. However when I retested this morning, with a key with no numeric characters, the autotext pop up worked normally, despite the autocorrection, which I guess is what you are seeing.
Thus it would appear that with this choice of keywords the autocorrect occurs before the key word is completed and the length of the keywords with respect to the number character may have been the issue, with two actions vying for precedence at the same character and it is that conflict rather than the autocorrect per-se that is the cause of the failure to fire the pop up?.
