Tactile popup
The tactile feedback popup is initiated/dismissed by the "T" key.
The line to alter is controlled by PageUp/PageDown or arrow up/arrow down and the settings changes by the "+" and "-" keys (just like threshold setting) and by the Left/Right arrow keys.
Any trace can be selected as the source of tactile data. The tactile mode can be OFF, 10 Hz, 60 Hz, or 160 Hz. This is the frequency of the signal being modulated by the source trace amplitude. Note that many laptops cannot produce 10 Hz signals due to poor audio systems.
