SQL Assistant - Suggestions

Hi, I have "Display Suggestions" turned on in SQL Assistant(15.00).  The problem is that when suggestions are displayed, the editor automatically autocompletes whatever I am writing when I press the space bar.  For instance, we have a view that is called something like "DISTINCT_THINGS", so whenever I start to type "select count(distinct " it corrects (incorrectly) to "select count(DISTINCT_THINGS ".
Is there anyway to change this autocomplete, so that it isn't activated by the space bar, but (for example) by the tab key, as I have seen done in other editor applications, so I can choose whether to accept the suggestion or not.
Thanks!
