     Thankfully, QMK supports [mod-tap](https://github.com/jackhumbert/qmk_firmware/wiki#fun-with-modifier-keys) keys, and this allows me to set the Enter key to send a modifier (MOD_LSFT) when held, and KC_ENT when tapped. Awesome!
 
+3. Escape
+
+    I am experimenting with using Left Shift as a mod-tap key for Escape, similar to how I use the Enter key. It's set up like this on my Minivan, so in the interest of consistency...
+
+4. Backtick
+
+    I don't currently have LEDs on any of my keyboards, and even if I did, I don't think I would want their controls on a base layer.
+
+    So, why use backtick in the lower left corner? I use it as my tmux prefix key, so I need to type it more frequently than most people. Putting it on the base layer works well for me.
