Predictive Text For Professional Typists

In Depth

Lightkey’s Adaptive Experience For Professional Typists

Lightkey calibrates it’s prediction interactivity in real-time based on the user’s typing speed. The faster the user is typing, Lightkey will suggest only higher-impact (multi-word etc.) predictions. While this mechanism is fully automatic and is activated by default, users can manually switch between prediction interactivity profiles in Lightkey’s Control Center. This feature is available and enabled by default only in our premium editions Lightkey Professional and Lightkey for Business.

Typing Fast? 5 Ways To Improve Your Performance With Lightkey


One of the most frequently asked questions we needed to address since we started developing Lightkey was about its relevance to fast typists. People often told us: hey, I’m typing really fast – can Lightkey help me become even faster and more productive? Here are the 5 reasons behind our clear-cut answer – YES, IT CAN!

#1 – Over Time, a single Keystroke Can Produce 12 Words

Lightkey redefines our approach to typing and thus involves some habitual change. However, as Lightkey learns your typing patterns, thanks to its innovative prediction capabilities, it will suggest longer predictions making every keystroke way more powerful and therefore increasing your typing speed significantly.

TheWindowsClub recently published a review on Lightkey addressing this issue directly: “It took me a while to get hold of the tool. Once I got a hang, things started to look up from there. My typing speed usually ranges from 50-60 words per minute. However, with Lightkey it increased to 80-100 words per minute”.

#2 – Real-Time Spelling Correction Is More Efficient Than Considering Alternatives

According to RataType, 8% of our keystrokes are mistyped. Once our eyes see these zigzagged red crosses suggesting that a typo was made, our line of thought is interrupted forcing us to go back and fix the typo.

Lightkey suggests the correct spelling of words while being typed just as we are used to when typing a search engine query. This helps preserve your focus on the content while facing forward rather than going back to correct. The result is higher typing efficiency and our smoother experience. Moreover, it enables a different mindset where you can type with confidence and elevate your thought process to focus on your ideas instead of being bothered by the typing mechanics.

#3 – Less Keystrokes May Reduce Wrist Pain

Excessive use of the keyboards (which is associated with professional fast typists) can result in wrist pain. The mathematics behind this is rather simple: For example, assuming a 10,000 word article means approx. 50,000 keystrokes, if you were to reduce the number of keystrokes to 30,000 to accomplish the task, that would necessarily mean less energy spent. Regardless of the time gained factor, typing less keystrokes can have a positive effect on your health.

#4 – High-Impact Predictions Based On Your Typing Speed

The time required to consider and accept a suggested prediction is an important part of the overall typing efficiency. This is why Lightkey was designed to suggest only a single prediction displayed inline with your text. Moreover, Lightkey has its own confidence mechanism that results in suggesting only when there’s a probability to make a positive contribution to the user. In other words, Lightkey was designed to make this process of considering a suggestion as intuitive and beneficial to the user as possible.

Adapting to fast typists, we took this design aspect to the next level. Lightkey includes an automated mechanism that detects your typing speed in real-time and adjusts its prediction interactivity in a way that only  suggests high-impact time-sensitive text predictions. The faster you type, the more Lightkey will focus itself on higher-impact predictions, attracting your attention only when the predictions are significant and worthy.

#5 – Get Full Control On Lightkey’s Contribution

We believe in making the default behavior of Lightkey as intuitive and simple as possible. However, there’s also a manual alternative for those who enjoy hands-on experimenting and custom configuration. If you wish Lightkey would suggest only high-impact predictions regardless of your typing speed, simply open the Preferences tab in Lightkey's Control Center and choose the prediction interactivity of your choice.

The “Fast Typist” setting is suitable for typing speeds of 60-80 WPM whereas the Ultra-Fast Typist setting is suitable for those who clock over 80 WPM. This feature is available only in our premium editions Lightkey Professional and Lightkey for Business.
