The native calculator app for Android has a "Clean history" option, but I have no clue on how to see this history.

I've tried swipe movements, clicked on every possible button and even to held down the menu button as described [here]( https://android.stackexchange.com/questions/19407/accessing-calculation-history-on-htc-calculator-app), but I could not make the on-screen keyboard show up.

Anybody had more luck trying this? I am running Android 4.4.
