Many mouse functions can be performed by keyboard accelerators (hot keys). The keys and their functions are:
| Function | Key |
|---|---|
| Select All | ctrl-a |
| Cut | ctrl-x |
| Copy | ctrl-c |
| Paste | ctrl-v |
| Delete | delete |
| Undo | ctrl-z |
| Redo | ctrl-y |
| Start Wire | ctrl-w |
| End Wire | esc |
| View Element Contents | ctrl-s |
| Watch/Unwatch Element | ctrl-w |
| Add/Remove Probe | ctrl-p |
| Modify Element | ctrl-m |
| Change Timing | ctrl-t |
| Lock Element | ctrl-l |
Many keys only work when the cursor is in a certain place (e.g., on an element, on a wire, in "empty" space) - otherwise they have no effect. The ctrl-w key is context sensitive: if the cursor is on an element that can be modified the function is "Modify"; if it is in "empty" space the function is "Start Wire".
