I agree with this post, it would be helpful to expand the context to include more words
When opening a new lesson, the words that you have not previously identified as "known" appear in blue. If you do nothing to them and turn the page, the software will assume you know them and add them to "known words." If you click on them, each turns yellow and becomes a "lingQ." You can do review exercises for them or not as is your choice. If you correctly choose the right answer for the word in the review exercises, the number (and color of the word on the page will change). You can manually change the number as well if you think you know the word.
Sometimes words that others have commonly also viewed as a phrase instead of a single word will appear in gray around the blue (or yellow) word. You don't have to click on the phrase if you don't want to, it is just a suggestion. If you just click on the single word, only it will become yellow and be identified as a lingQ for review. By turning the page, the other words (gray included) will become part of your "known words."
In addition, you can create phrases as lingQs by dragging your cursor over the words you want to make into a lingQ in the same way if you wanted to highlight a portion of text and then move it or delete it. (That is, depress the mouse pad with your left hand as the right hand drags the mouse across the words you want to include. The words should turn yellow. Lift up your left hand from the mouse hand to end the words included.
You should see the phrase you wanted to highlight in yellow in the text and they will appear in the lingQ window to the right as a phrase. You will be prompted for review of these phrase lingQs in the same way as for single words. I routinely make lingQs of short phrases of idiomatic expressions and for verbs that have different meanings when combined with different words. If you want to make a lingQ of longer text, I suggest that you nevertheless break up the passage into logical clauses (e.g, the ones separated by commas) as this will make it easier to remember and review them in exercises.September 2018
Thanks for replying but, unfortunately, none of this is relevant to what the OP is talking about. He/she wants what's called the 'Original Context' around the LingQ (whether single word or phrase) to be editable. That is, if you look at your LingQs in your vocabulary section, there is a 'phrase' which shows you where you first saw this LingQ (whether single word or phrase) by giving you part of all of the sentence the LingQ originally appeared in. The OP would like to be able to expand this phrase because sometimes it is just part of a sentence and in those cases it might not give you the LingQ's context in a meaningful way.September 2018
