Font size decreases when pressing only the CTRL key after using my trackpad to
scroll (from the middle of a page) to the top or bottom of the page.  A good
example is when reading a page, and scrolling to the bottom.  Press CTRL (in the
process of pressing CTRL-L) and the font size for that window will decrease. 
Does not matter if it is in a tabbed window or a "complete" window.
This only is confirmed with my Synaptics PS/2 trackpad when I "auto-scroll" to
the end of the window.

Reproducible: Always

Steps to Reproduce:
1.Scroll to top/bottom of window from middle of page (hands-free scroll)
2.Press CTRL button
3.

Actual Results:  
Text size decreases.

Expected Results:  
Nothing to the text size (unless I had pressed "-" in conjunction with the CTRL key.

This is intentional behaviour and therefore not a bug.

-> INVALID

Comment 2

[Arjen Dragt]

This cannot be intentional behaviour.  I understand that pressing CTRL + the "-"
key should decrease my text size, but why simply pressing the CTRL key?  How
does that make any sense?  How is one supposed to press "CTRL-L" to get to the
location bar if this is the design?

Text increases and decreases not only when you press CTRL + or - but also when
you press CTRL while scrolling with the mousewheel. Since scrolling with the
trackpad is the equivalent of mousewheel scrolling this is intentional behaviour.
