  Touch-based devices, despite their mainstream availability, do not support a
unified and efficient command selection mechanism, available on every platform
and application. We advocate that hotkeys, conventionally used as a shortcut
mechanism on desktop computers, could be generalized as a command selection
mechanism for touch-based devices, even for keyboard-less applications. In this
paper, we investigate the performance and usage of soft keyboard shortcuts or
hotkeys (abbreviated SoftCuts) through two studies comparing different input
methods across sitting, standing and walking conditions. Our results suggest
that SoftCuts not only are appreciated by participants but also support rapid
command selection with different devices and hand configurations. We also did
not find evidence that walking deters their performance when using the Once
input method.
