  • Is it possible to configure Lightkey’s selection key (e.g. 'Space Bar' instead of Tab)?
    Yes, you can choose either Tab, Enter, right arrow or all three of them as your selection key/s. We chose Tab as Lightkey’s default selection key for reasons derived from some of our core values: (1) minimum interference with the user’s typing; and (2) minimum false positive errors. For example, choosing ‘space bar’ over Tab as Lightkey's selection key would evidently result in both unwanted interference and false positive errors. In other words, using ‘space bar’ as the selection key might result in selecting predictions where such predictions are unwanted. For example: let’s assume you want to type the word ‘attach’ and Lightkey suggests the prediction ‘attached’. You ignore the suggestion and after typing the last character ‘h’, you press the ‘space bar’ in order to create a space and move on to the next word. If ‘space bar’ was Lightkey's selection key, at this point Lightkey would recognize the ‘space bar’ hit as your order to select its suggested prediction, and instead of getting that space and moving on to the next word you would end up with ‘attached’ instead of ‘attach’. Also, it should be noted that Tab is actually very commonly used as a selection key in many development platforms such as software development etc.
  • Can Lightkey work in conjunction with Google's Smart Compose in Gmail?
    Unfortunately, due to the fact that Google’s Smart Compose feature UI is highly similar to Lightkey's UI (i.e. inline text predictions, displayed in gray font), there might be a conflict that affects the way predictions are displayed. In order to solve this issue, we recommend users to choose which prediction solution they prefer for typing in Gmail, and simply deactivate the less proffered solution.
