     Look up (control l)-
	 
	 This does the main function of the query tool.  This will do a match of all instances in the class that match the limitations given in the entry bars.  A blank field here implies match all. i.e. if you there is a field year of type int and you put a 93 there then click look up you will get all instances where year=93. If you put 93 94 you will get year>=93 and
year <=94.

        if you have a field lastname of type text and type in figel you WILL NOT get any instances where lastname="Figel" as the search is case sensitive, but you will get instances that figel is a substring like x.lastname='Smithfigelonsky'  Apoligies to anyone with that as a lastname, Figel is bad enough.  (BTW it is pronounced FEEGLE)
