This is a neat trick but it will select the whole 'paragraph', which in most logs means the entire row. Triple click the following:
b214a2bb-c3c1-48fb-8272-10a2808337f3, something, ...
b214a2bb-c3c1-48fb-8272-10a2828337f3, something else...
b214a2bb-c3c1-48fb-8272-10a2808337f3, something, ...
b214a2bb-c3c1-48fb-8272-10a2828337f3, something else...
Not as good as double-click selects all the id, but at least id doesn't take too much time and I don't have to precisely go to one of the ends.
