How to set option for search & replace

<font face="Arial">Hi,<br /><br /> where can I set the options for search & replace as defaults for the
SQL-editor?<br/> I generally need to replace stuff "from start" and "case sensitive" instead of "from cursor
position".<br/><br /> I recently installed PG new on this box and I can't remember where I could define those
options.<br/><br /><br /> regards<br /> Andreas<br /></font>
