When using iPad it is easy to highlight text (in say, yellow) for future reference. Can the same thing be done when using a PC?
Yes. see https://wiki.logos.com/Highlighting
And what is great is that your highlights can be viewed on multiple platforms.
It depends upon what you mean by "easy." It isn't difficult to highlight in L6, and it can be made fairly simple with keyboard shortcuts, but it is still a two step process. You can't have highlighting auto applied simply by swiping as on mobile. The Link MJ provided should give instructions. Let us know if you have more questions.
Thanks for the assistance. Yes it works well. Having set a shortcut (Y for yellow) key to highlight, is it possible to set a shortcut key to remove the highlighting? I have tried Y with CMD, Option Ctl & Function, but none will remove the highlight. It appears that the only way to remove the highlighting is using "erase" in the highlighting box.
is it possible to set a shortcut key to remove the highlighting?
Sorry, no.
