Easy Log function on a TI-89 Titanium

I know this is outside of the normal topics discussed on this site but I felt a serious need inform others about hidden functionality on the Texas Instruments TI-89.

Recently in my math class I was required to use the log function on my TI-89 Titanium. I couldn’t find it except by using the catalog. I read the manual and searched on the internet, I couldn’t find a better method, I in fact fount a lot of worse methods. So sitting in class I started pushing the alternate function keys and pressing all the keys without their alternate function listed. The calculator does in fact have a quick key for the Log function. Diamond & 7

    Just one more example of the cryptic input for the TI-89. Shame on Texas Instruments.

    Awesome find! Been searching online for this shortcut, glad someone found an easier way than scrolling through the catalog

    I pressed diamond & 7 for log function. But I am not able to get it in TI 89. when I checked it using diamond EE, 7 has been assigned to some other KBDPRGM. How can I set it to log?
