Multi-select: Add/remove single block to/from selection via modifier key -- CMD on Mac / CTRL on Windows/Linux

[porg]

Usability Foreword

Selecting multiple elements, efficiently adding/removing to that selection, and then eventually move/edit the whole selection is a crucial function for WYSIWYG design software.

I) Continuous selection — From first til last via SHIFT key

1. Click first element in left side tree pane ("Document Outline" ) or on canvas.
2. Hold down the ⇧ SHIFT modifier key.
3. Click last element in tree pane or on canvas.

Expected Outcome: Selects all elements from first to last (as in tree pane order, not necessarily equal to visual order)

• Implemented in very early issue: Multiple block selection #62

• ✅ Mac Chrome

• ✅ Mac Safari — Was improved just recently in Safari: fix Shift+Click multi select #53440

II) Add to / remove from selection — Via other modifier key

1. You have an existing selection — Single clicked block, or a selection from a mix of method(s) I or II.
2. Hold down the add/remove modifier key (⌘ CMD on Mac ; ⌃ CTRL on Windows/Linux)
3. Click unselected element to add it, click selected element to remove it.

• ❌ Not supported in the browsers that I tested: Mac Safari, Mac Chrome
• Related: Select Many Blocks Via Dragging #41684

Video which shows that continuous selection with ⇧ works but add/remove to/from selection via ⌘ does yet not work

I think you are asking for non-consecutive multi-selection? So this would be a duplicate of #16797?

@ellatrix what I asked for is indeed a duplicate of #16797 which goes even beyond the selection process itself but also discusses how to handle the move operations of the non-consecutive multi selected items then.

I'm glad that the core team is aware of the lack of this feature. Hence I'm closing my ticket.
