The Esperanto Quick Reference 1.0 is a list of essential words that all Esperanto speakers should learn, together with English translations, packed onto four pages. Please let me know if you feel that a common Esperanto word is missing from the quick reference.
Windows users: looking for a way to type the letters ĉĝĥĵŝŭ with the hats on them? Download my Esperanto/Spanish/English keyboard layout for Windows. It mostly acts the same as normal English keyboard, but you can hold down the right Alt key and press cghjsw to get the Esperanto letters ĉĝĥĵŝŭ (and you can hold down the right Alt key and press aeioun to get the Spanish letters áéíóúñ). Shift+Right Alt gives capital accented letters, kompreneble.
