Only one shortcut (accelerator) should be required to both interactively select multiple features and deselect features from the current selection. In ArcGIS Desktop (ArcMap) this was accomplished by holding down the Shift key for both actions. ArcGIS Pro requires holding Shift to interactively select multiple features and holding Ctrl to interactively deselect from the features selected. Why require 2 different shortcuts keys when 1 worked perfectly in ArcMap? Please allow both actions to be performed while holding down the Shift key like it was in ArcMap.
