Repeating the last selection can be useful. For example:
Sometimes you apply changes to several selected objects simultaneously. To properly appreciate the result and avoid clutter, it is necessary to temporarily deselect, and then select again if further changes are needed.
Sometimes you apply changes to a selection and accidentally click on the background or something else, hence losing the selection. If the selection were really complicated you should have created a group for it, but if it is just a few objects you may feel that it is not appropriate to create a group.
Is there a way to recover or repeat the last selection in Inkscape? I have seen a couple of threads on other forums such as this one and this one that seem to indicate that it is not possible, but they are a decade old, so new features may have been added since then.
