## tool

Change layout tool or print information about what the button bindings are for the current tool. This page describes the tool command as implemented in the non-Tcl version of magic.

### Shortcuts:

> Key macro space implements the command tool.
> Key macro shift-space implements the command tool box.

### Usage:

> tool [name|info]

> > where name may be one of box, wiring, netlist, or rsim.

### Summary:

> The tool command selects or queries the mode of operation of the mouse buttons in the layout window. Each tool type has a unique set of button bindings.

> Without arguments, the tool command selects the next tool type in round-robin fashion. With a tool type as argument, the button bindings switch to those for the indicated tool. With the info option, a summary of the mouse buttons is given for the current tool.

> The mouse bindings for each of the three tools is as follows:

> - Box Tool
>   left
>     Move the box so its lower-left corner is at cursor position
>   right
>     Resize box by moving upper-right corner to cursor position
>   middle
>     Paint box area with material underneath cursor
>   In addition, you can move or resize the box by different corners by pressing left or right, holding it down, moving the cursor near a different corner and clicking the other (left or right) button down then up without releasing the initial button.
> - Wiring Tool
>   left
>     Pick a wiring layer and width (same as "wire type")
>   right
>     Add a leg to the wire (same as "wire leg")
>   middle
>     Place a contact to switch layers (same as "wire switch")
> - Netlist Tool
>   left
>     Select the net containing the terminal nearest the cursor
>   right
>     Toggle the terminal nearest the cursor into/out of current net
>   middle
>     Join current net and net containing terminal nearest the cursor
> - Rsim Tool
>   left
>   right
>   middle
