+<p>
+ To the left of the name of each processor is a small LED symbol; if this is lit-up, the processor is active.
+ <kbd class=mouse>Left</kbd>-clicking on the LED symbol, or <kbd class=mouse>Middle</kbd>-clicking anywhere on the processor
+ will deactivate the processor and effectively bypass it. Click again to reactivate the processor.
+</p>
+
+<p class="note">
+ Some processors have their own bypass controls that are independent of the one that Ardour provides; this can make it appear
+ that the plugin is non-responsive when its independent bypass control is active.
