The Selection Editor
SelectionEditor.exe is a program installed in your install directory, which is used for editing your selectkeys.txt configuration file, allowing you to make your own shortcut keys for selecting/filtering selection.
This forum topic that should be duplicated here, with cleaning up and additions made... and permission probably.
Default Selection Controls
Unless you have issued a pending command, left-clicking(Mouse Button 1) a unit will clear the current selection and select the left-clicked unit, if a spot with no valid selection is clicked(empty space, ground, unowned units), the current selection will just be cleared. Left-clicking and dragging will draw a box, any units within this box will be selected when you release the mouse button.
Shift+Left-clicking(including dragging a select box), unless you have a pending command, will add units to the current selection.
CTRL+Left-clicking (including dragging a select box), unless you have a pending command, will remove units from the current selection.
Double-left-clicking will select all visible(camera bounds) units of the clicked type(Shift+Double-left-clicking will add the double-clicked units to the current selection).
CTRL+Z is a filter (which can be eddited in Selection Editor) to select all owned units of the current selected type. For example, if a peewee and a brawler are selected, all peewees and brawlers will be selected.
"Tooltips" are displayed in the bottom left of the current interface, if units are selected this information is the sum of all information about the selection (aka, select a bank of 5 solar collectors and it will show the total health and total energy being produced). If you mouse-over a "build-pic" in a units command list it will show you the costs and stats associated with the unit represented by the "build-pic". If you have no selection, the tooltip will show information about what your mouse is over at that time (unit stats if it's a unit, otherwise information about the terrain).
