Qonvert v1.9.0 (♯13) – Cheat sheet

Gestures

• Output area: short-tap copies to input line and switches input and output bases, long-tap copies to clipboard.
• Base buttons: left/right swipe decreases/increases base by 1, long-tap brings up dialog for choosing a base.
• “in: base” and “out: base”: tap displays digit range for currently selected base and number system.
• Number system buttons: long-tap toggles between standard and balanced.
• Base sliders: sliding all the way to the right brings up dialog for choosing a base.
• Clear button (🗑): long-tap sets input and output to standard decimal.
• Qonvert keyboard: long-tap accesses the second character on a key; ◀ or swiping down vanishes it, and tapping the input line lets it re-emerge.
• List entries in history etc.: short-tap copies to input line, long-tap toggles selection. In selection mode, long-tap selects a range.
