Master Lightkey with these 5 Tips & Keyboard Shortcuts



Lightkey was designed to increase your productivity while maintaining a short learning curve. However, using the following tips can take your Lightkeying skills to the next level even faster.

Tip #1: Keep on typing even if you think you have spelling mistakes

Many users type their google searches without caring much about spelling. For example, if you type “avuoiding speplliing mismsitakes” in google search it will offer you the query in its correct spelling form “avoiding spelling mistakes”.

This feature significantly improves the ‘google search’ user experience.

Lightkey brings a similar user experience to other platforms used for typing. Lightkey’s spelling correction technology enables you to keep on typing and regardless of your certainty of the correct spelling, Lightkey will most probably offer just what you need.

Just type & TAB and let Lightkey do the rest.

Tip #2: Use Lightkey’s variation technology

In some cases, Lightkey will offer the correct word but in a different variation from the one you intended. For example, Lightkey might offer the word 'predicted' whereas you wanted to write 'predictions'.

Lightkey’s “Variation Technology” was developed to solve this. Using CTRL + arrows enables you to navigate between shorter variations (CTRL+LEFT), longer variations (CTRL+RIGHT) or different variations (CTRL+UP or CTRL+DOWN) of the suggested word. Watch the following video to see how it works in real-time:


Tip #3: Use the “wishful tab” technology

Lightkey gradually adapts itself to your typing style. As your interaction with Lightkey becomes more fluent you’ll reach a point where you feel you know when Lightkey is about to offer the right suggestion. In which case, feel free to press the TAB key even if no suggestions are displayed on the screen; Lightkey will recognize your TAB keystroke as a “suggestion request” and prompt its best possible prediction match. Press the TAB key again to select the suggested prediction.

We call this feature “wishful tab”. Be bold; press TAB on-the-go and see if Lightkey knows you well enough.

In order to provide you with smart tab without taking away the existing functionality, the wishful tab technology will be available only following an alphanumeric keystroke and outside tables as TAB is used to move between table cells.

Tip #4: Use CTRL+SPACE to accept predictions without the following extra space

This tip is best explained with an example: You want to write the word “demonstrates” - You start typing and after typing “dem” Lightkey offers the word “demonstrate”.

There are a few options to get there from this point:

  1. Lightkey's Variation Technology – explained in tip #2 – press the CTRL+RIGHT key combination to get a longer variation, however there is a chance Lightkey might suggest a different variation from the one you intended (e.g. “demonstrated”).

  2. The manual way – press TAB, use Backspace to delete the extra space and add the “s” character.

  3. Our recommended solution – Lightkey’s CTRL+SPACE key combination – by pressing CTRL+SPACE Lightkey will add its suggested prediction just as if as you pressed TAB keeping the cursor at the end of the word – i.e. without the following space at the end of the word – allowing you to just type the missing “s”.

Tip #5: use CTRL+1 … CTRL+4 to accept predictions avoiding some of the last ending characters

This tip will help get over situations where you actually intended to type a word which is a bit shorter than the one suggested to you by Lightkey. Again, this is best explained with an example:


You want to type the word “projection”.

Lightkey offers the word “projections”.

Again, there are a few options to get there from this point:

  1. Lightkey's Variation Technology – press the CTRL+LEFT key combination to get a shorter variation, however there is a chance Lightkey might offer you a different variation from the one you need (e.g. “projected”).

  2. The manual way – use TAB to accept the entire word “projections” and manually use Backspace to delete the last “s” character.

  3. Our recommendation developed to solve such situations – by pressing CTRL+1 (the digit 1 on the keyboard) Lightkey will accept the offered suggestion omitting the one last character (i.e. projection). Similarly, by pressing CTRL+2 Lightkey will accept the offered suggestion omitting the last 2 characters (i.e. projectio), CTRL+3 means accepting the offered suggestion omitting the last 3 characters (i.e. projecti), and so on.
