With the release of 2023r1, a feature I’ve been harassing urging the Xojo team to add is finally here: the ability to move or duplicate lines in the editor via the keyboard.
With your cursor anywhere in a line, try option-up/down to move the line.(alt-up/down on other platforms.) Add shift into the mix to duplicate that line in the direction of the arrow.
This will change your life. 
only because I had head start
Or type faster? 
I confess: I just read a tweet about it, and wondered how ‘copy and paste’ was a feature deserving of an exclamation mark in 2023.
Looking forward to having my life changed…
Sadly agreed. Not only I don’t need these new features, but I’ve seen times where I just wanted to change the current selection/insert point using the keyboard and ended up duplicating a line by mistake. By typing fast, I was almost not noticing this.
An option to turn this off would please me.
