Andre,
It used to bother me that it was difficult to find the end element of an array, but there is a solution! Right click on the array, and select "Visible Items -> Show Vertical Scrollbar". This works on FP arrays and BD constants.
Cheers,
Jack
While we're at it with keys operating on Arrays, how about "PageDn" and PageUp" moving up (Index-wise) and down the visible Array elements by the same number as Array elements are visible.......
Keyboard shortcuts for inserting into and deleting from arrays were added to LabVIEW 2020 SP1.
