Dactyl ManuForm 4x5

I've been using the Dactyl Keyboard, available at https://github.com/tshort/dactyl-keyboard, and I must say it's a remarkably small and extremely portable keyboard perfect for basic communication needs. However, there is one significant drawback: the absence of a top row makes memorizing symbols an excruciating task, rendering it nearly impossible to code with this tiny device.
