That is correct. Shift + Right click will select first flower option.
As of late I have been working very hard for 2 weeks trying to implement text selection for copy pasting. But I really have reached the limitations of my patience cause its really difficult to make it work. Im still working on it and will try push the update out when I actually get the selection to work properly.
Just a few teaser pictures of the selections mechanics.


The problems I'm facing with the selection boxes are the hardest ones I have ever had to work with. But I have thought long and hard for solutions and am hopeful that I will fix them soon.
Exams are coming soon so I hope to have it finished before. If I don't find a fix I will upload the changes I have worked on to Github if anyone requests it so others might be able to help find solutions.
Right now I can select a specific text in the text entry boxes to both select edit and manipulate the selected text. There are still bugs related to it but I will have to work out the kinks with the bugs. The more difficult problems are in the actual text field seen on the second picture. Making selection boxes on a text area is proving to be extremely difficult because of how the text mechanics are coded then edited both by Ender and myself later on. Shows to prove bandage solutions really come to bite you in the ass down the line.
