Iambic Keying -- also known as "squeeze keying," the technique of squeezing the levers
together to use the iambic features of the keyer. There are two kinds of squeeze.
True Squeeze: if both paddles are held closed, the keyer will send an alternating string of dots
and dashes, starting with which ever (dot or dash) was closed first, if only my a millisecond. For
example, to send a period (di-dah-di-dah-di-dah) you would squeeze the levers together, making
sure that the thumb or dit lever closes slightly ahead of the dah lever, wait for the keyer to send
di-dah-di-dah-di-dah, and release the squeeze.
The second type of squeeze is “character insertion” where one paddle is held closed and the
other is tapped to insert the opposite element into the string. For example, to send the letter F
(di-di-dah-dit) you would hold the thumb or dot lever closed, wait for the keyer to send the
second dit, and “tap in” a dah without releasing the dot lever. Technically it is still a “squeeze” to
the extent that both levers are closed for a brief moment, but the student usually learns these as
two separate techniques for different types of characters
