Gateway MD73 series Laptop [Fn] key symbol meanings?

Recently got this laptop (Gateway MD7336u) and want to know what each of the [Fn] keys are for and what they do. Here is a list and description of the ones I don't know. F1-Half lit light bulb with light coming out of the unlit side. F2-Pretty sure this is a WiFi antenna. F3-Crescent Moon. F4-Two rectangles separated by a /, the left one has an outline. F6-One symbol looks like a sideways V pressed against a B that is two triangles. F8-Sun with half solid half hollow with a - on hollow side and + on solid side. Up arrow- Solid sun Down arrow- Empty sun I know what Break on pause key is and PrtSc on Insert is print screen but on the delete button it say SysRq and don't know what that one is. Can you tell me the meanings to these symbols? I know I have to use the [Fn] key to use them but I don't know what they are for.
