## Using Multi-Tool

To use Multi-Tool Mode, click the button on the Tools Toolbar or press F6 on the keyboard.

Multi-Tool Mode automatically selects one of the four tools on the Tools Toolbar according to mouse moves and key presses. The mouse pointer changes to show which of its functions is currently available (the pointer will appear similar to the button for the relevant tool on the toolbar).

## Selection Tool

## Envelope Tool

| Note carefully that there is a bug whereby when using some effects on tracks that have envelopes, then the envelope is removed and the audio reverts to its full amplitude state prior to the effect being applied. Notable among these are the filters and the EQ effects. The workaround is to apply the envelope prior by using Mix and Render prior to using the problem effect. Please see Envelope Tool for a list of the effects that this bug impacts.

## Draw Tool

Draw Tool is made available by zooming in until you can see individual samples then hovering the mouse pointer close to the line joining the samples. The pointer then changes to a pencil tool and you can use it as you would use the standalone Draw Tool.

### Zoom out

Right-click (Ctrl + click on a Mac) the mouse at a point to zoom-out by a factor of 2, centered on the click point.

Note that even though you are zooming out the zoom cursor magnifying glass inconsistently shows "+" zoom-in iconography.

### Zoom in

Right-click, drag and release to zoom-in to a drag-selected region.

| If you commence a horizontal or vertical drag to zoom by mistake, you can press Esc before releasing the mouse button to cancel the zoom operation.
