+- Click with the mouse anywhere on the waterfall display. The green Rx
+frequency marker will jump to your selected frequency, and the Rx
+frequency control on the main window will be updated accordingly.
+
+- Do the same thing with the Shift key held down.  Now the red Tx
+frequency marker and its associated control on the main window will
+follow your frequency selections.
+
+- Do the same thing with the Ctrl key held down.  Now the both colored 
+markers and both spinner controls will follow your selections.
+
+- Double-clicking at any frequency on the waterfall does all the
+things just described and also invokes the decoder in a small range
+around that frequency.
+
+- Now double-click on any of the the lines of decoded text in the main
+window.  Unless you have *My Call* set to K1JT or KY7M on the
+*Settings -> General* tab, all three lines will show the same
+behavior, setting both RxFreq and TxFreq to the frequency of the
+selected message.  However, if MyCall is set to K1JT then clicking on
+a message directed to K1JT will move only the Rx frequency setting.
+This behavior is desirable so that you will not inadvertently change
+your Tx frequency to that of a tail-ender who called you somewhere
+else in the FT8 subband.

 IMPORTANT: When finished with this Tutorial, don’t forget to re-enter
 your own callsign as *My Call* on the *Settings | General* tab.
