When you start a selection tool, you can shift-click (instead of plain 
click) to add the resulting selection to the current selection (instead 
of replacing it). You can also make several successive selection, saving 
them to a channel each time, and then combine them at the end

You can select the pixels with a given color using the color selector. 
You can also use that selection tool with specific selection criteria 
(Hue, Saturation, Value, specific RGB channel).
