+/* Return an integer that corresponds to what kind of tap dance should be executed.
+ *
+ * How to figure out tap dance state: interrupted and pressed.
+ *
+ * Interrupted: If the state of a dance dance is "interrupted", that means that another key has been hit
+ *  under the tapping term. This is typically indicitive that you are trying to "tap" the key.
+ *
+ * Pressed: Whether or not the key is still being pressed. If this value is true, that means the tapping term
+ *  has ended, but the key is still being pressed down. This generally means the key is being "held".
+ *
+ * One thing that is currenlty not possible with qmk software in regards to tap dance is to mimic the "permissive hold"
+ *  feature. In general, advanced tap dances do not work well if they are used with commonly typed letters.
+ *  For example "A". Tap dances are best used on non-letter keys that are not hit while typing letters.
+ *
+ * Good places to put an advanced tap dance:
+ *  z,q,x,j,k,v,b, any function key, home/end, comma, semi-colon
+ *
+ * Criteria for "good placement" of a tap dance key:
+ *  Not a key that is hit frequently in a sentence
+ *  Not a key that is used frequently to double tap, for example 'tab' is often double tapped in a terminal, or
+ *    in a web form. So 'tab' would be a poor choice for a tap dance.
