The standard Czech layout is QWERTZ (Y and Z swapped) with the accented letters on the unshifted number row: + ě š č ř ž ý á í é across 1 to 0, and digits on Shift. ú sits right of P with ) beside it, ů and § are right of L, and the dead keys ´ ˇ and ¨ provide the remaining accents. The top-left key is ; °. AltGr reaches @ # $ & { } [ ] \ | and the Euro sign. The board is ISO with a tall Enter and an extra \ | key beside the left Shift.
Press every key and watch each cap count one per tap. The number row is the busiest: test it unshifted for the accented letters and with Shift for the digits. Press the dead keys ´ and ˇ on their own — the tester registers the switch immediately. Check the ISO-only keys beside the left Shift and beside Enter, and try AltGr with the letters that carry programming symbols.
That is by design: on a Czech layout the digits are on Shift. If you want unshifted digits, most people either use the numeric keypad or switch to the “Czech (QWERTY)” or programmer variants. The hardware is the same — this tester shows every switch working regardless of the mapping.
