A patch change is Ardour's description for a combination of MIDI program change and bank select messages, that (typically) instruct a synthesizer or sampler to select a different sound to use on a particular channel.
Patch changes are shown within MIDI regions as small rectangles or flags, with a vertical line showing where in the region (hence "when") this patch change happens.
To insert a patch change, the edit point should be located where the patch change should be (within an existing MIDI region). When right clicking, and from the MIDI region's context menu, selecting MIDI > Insert Patch Change, a dialog appears allowing to set the bank and program values.
Context-clicking on a patch change will bring up the same dialog that was used to create it, allowing to modify the program and/or bank numbers.
The mouse wheel can also be used: ⇑/⇓ on the patch change will alter the program number, ⇑/⇓ will modify the bank number.
Just Left-dragging the patch change moves it around.
Pressing Del with the mouse pointer into the rectangular area, or using the delete mouse button operation will remove the patch change (the operation can be undone).
