| <p>The format of a regular expression can be rather complicated. |
| To make sure you didn't miss some slash of quotation mark, place the caret |
| somewhere in the expression you want to check, and press <span class="shortcut">&shortcut:ShowIntentionActions;</span>. </p> |
| <p>In the pop-up frame type a string that you think should match your regular expression. If the background turns green, you are lucky. If it turns red, then you have to look for a mistake. </p> |
