[Feature Request] Triple-click to select an entire line of text

[gurkan-komurcu]

In many text editors and document viewers, users can select text with simple mouse patterns:
Double-click → select a word
Triple-click → select the entire line
Currently in SumatraPDF, double-click selects a word, but triple-clicking does not select the full line of text. As a result, selecting a full line requires manual drag selection.
Triple-clicking would be a small but impactful usability improvement.

Hmm this is a duplicate of several requests and the underlying reason it is not "easy" is that in a PDF there is no real concept of words or lines of text. The detection of a word requires combine letters of similar elevation on the page into a group (word) and look for a significant difference each end (a word boundary) then a double click can export that part object. For a line the extension would need to consider all items to page boundary, thus not impossible but harder to define. So not a good example but look at the most recent comment #5361 (comment) where each letter group is not cleanly defined , although you could argue double click could select Lorem and ipsum
