How Do you Delete Units?

[Adun]

I placed some hostile units where I don't want them, but I spent a long time creating the map after that. Now I can't just spam undo because I'll undo literally everything i've done past that point. I just have 3 orc warlords (Orcs riding horses, not wolves) that I want to move. What can I do>

Select them (left click or drag selection) and press delete.

More specifically, select the Unit Palette on the Tool Palette (which puts the editor into unit editor mode), then click the Selection Brush on the main toolbar. Then select the units and delete them.

Since all user friendly ways have already been mentioned...

One can also modify the doo file, where the units are declared, programmatically. Several APIs have been made to let one do this.
