Then maybe you should change to a different EDA software to improve your health.
Will improve the spirit first, health later! I have used KiCad for barely two days now but find the hierarchical sheets better than what PADs of yore offered, so I’m in no hurry to worry about health
And to come back to my point, I may be missing something; but – having learnt the use of hotkey ‘C’ for copy, I found that it didn’t work across sheets, so that was a little suprising. (The users who got used to the interface may find it less surprising over time, that is but natural).
Now say you realize you need to click and drag to explicitly select a symbol (a “block” of just one thing) and then you press ‘C’, EEschema does not copy it. You have to press Ctl-C instead (agreed it is in every other UI, no issues there). But a hotkey user would expect ‘C’ to copy the block which is already selected, and it didn’t, that’s the second surprise.
If hotkey ‘C’ would work consistently, that is the fastest and I would use that, but now I have to remember that I am going to copy across sheets, hotkey ‘C’ would not work there and therefore I should use the copy-block mechanism even when I am copying a single EDA symbol. And that blocks need Ctl-C and Ctl-V, and the hotkey ‘C’ does nothing for a block. These are in my opinion, not exactly consistent.
When you select text in any GUI word processor, you use the same operation whether it is a single character or a bunch of words, everything works consistently no matter what the extent of your selection, and no matter what the target to which you will paste it (later). I think users find that relatively more wholesome due to the consistency of the UI.
