A pen is a class 3 lever - the effort is applied between the load and the fulcrum.
A ballpoint pen contains a simple machine called a lever. When you click the button at the top of the pen or press the pocket clip to extend or retract the pen tip, you are utilizing a lever mechanism.
A pen is an example of a third-class lever, where the effort is applied between the fulcrum (pivot point) and the load (writing tip). The force applied to the pen causes the load to move.
A pen can be considered a lever because it has a pivot point (fulcrum) where you hold it, a point where force is applied (effort) when writing, and a point where the pen contacts the paper to create the writing action (load). By applying force at one end (effort), the pen's design allows it to create a writing action at the other end (load), making it function like a simple lever.
A pen is not typically considered an example of a lever. Levers are typically solid objects that pivot around a fixed point called a fulcrum. Pens don't operate in this manner for the purpose of writing.

There is a little plastic lever that engages inside the pen to hold it firm in the "out" position. The click is that lever dis-engaging and snapping free from where it was held.

No. The classic simple machines are: Lever Wheel and axle Pulley Inclined plane Wedge Screw Using the pen has no mechanical advantage, other than in a ballpoint pen where the roller bearing reduces friction, but is primarily intended to produce an even ink application.
A pen is a class 1 lever where the fulcrum is at one end, the load (resistance) at the other end, and the effort (force applied) in between.
Owners manual Page 68: If the engine continues to run after the ignition key is turned off, open the hood and push down on the lever marked ¨Stop¨until the engine stops running. Using a pen or a screwdriver or a pen should make it easier to push the stop lever down. This makes the engine choke.
A ballpoint pen is a writing instrument that uses a small rotating ball at the tip to disperse ink onto paper as it is moved across. It is a type of mechanical device that allows for precise and controlled writing.
A ballpoint pen is a simple machine because it utilizes a lever mechanism to transfer force applied at one end (when the user pushes down on the pen) to the ballpoint tip at the other end to create writing. The ink cartridge inside the pen also acts as a type of wedge, allowing ink to flow smoothly onto the paper.
I presume you are referring to an old fashioned fountain pen that you fill from a bottle of ink. There is a small flexible rubber sac inside the barrel of the pen which can be compressed by a lever. When the lever is released a partial vacuum is created in the sac that sucks up the ink. I haven't used one in years but remember having received one as a gift from my grandmother when I graduated from high school. There is a very nice article in Wikipedia about these types of pens:
