[TxMt] Skip snippet autocompletion

[Andreas Wahlin]

Let's say I write img<tab> and then I get the img tag with three  
attributes to fill in, let's say I want to skip the class attribute,  
how do I do that? Somewhat intuitive (to me) would be to just hit  
backspace after the switch to that attribute. So the keytype
img<tab>img.jpg<tab>image<tab><backspace>
would produce the following code
<img src="img.jpg" alt="image" />

Is there something like this?
