	Double-click from the list to edit a script.  Any changes are automatically saved. Drag images to insert full path at current position. Click Run to run them. New (also in context menu) to save current script and clear text editor (Unsaved will be in Untitled.js)
Combo Inserts:  Select one, then right click and select "Insert Template" in the context menu to insert it at the current cursor position. <Color>              Inserts a Gdi.Argb(...) after color is chosen. Clicking on the image before inserting can set the starting palette color. <Filename>         Inserts a 'Full path\\filename' or folder after chosen.  <Font>               Inserts a Gdi.Font( name, size, properties) after selecting OK on a font chooser. <x, y, w, h>        Inserts last clicked position in image display.  Click for just x, y, or press hold drag release for x,y,w,h. < x1, y1, x2, y2>  Same as above but inserts absolute position for x2, y2. The rest are templates.
