OSX 10.11.6 using trackpad, FF 6.004 beta
Using any filter as an example, do the following:
1) Edit the filter.
2) Sel ect the zoom tool for the component view.
3) Move the magnifying glass/+ cursor over the component view (over the image). Do NOT move the cursor.
4) Hold down the Option key and click the component view (image). It zooms in. This is incorrect.
5) While holding down the Command Key move the cursor. You will see the cursor change fr om + to - (for zoom out).
To summarize, if you do not move the cursor when zooming the component view, then hold the Option key down the Zoom state does not change. Minor but annoying if you click/type quickly.
