title: How to use expressions in PhpStorm Live Templates?
body: <p>I would like to speed up my coding using PhpStorm's Live Templates. I am a bit frustrated, because it seems to have a bug (at least on my system), as I can not make use of variable expressions, as described in the manual and other tutorials.</p>
  
  <p>Here are my 2 issues:</p>
  
  <ol>
  <li><p>I add an expression to a variable, then I want to delete it. I select it, delete it, hit <kbd>Tab</kbd> and it's back again => I don't know how to empty the expression field.</p>

  <li><p>I would like to enter an item name once and use the capitalize expression to fill out another variable. I have seen this done in a LaraCast tutorial, but when I enter the variable name it just disappears (I press <kbd>Tab</kbd> after entering the variable - if I press <kbd>Enter</kbd>, it just closes the dialog box, but the variable is still not saved).</p>

  </ol>
  
  <p>Does anybody know what I am doing wrong or if this is actually a bug?</p>
