This is why we used to have customizable toolbars, and relevant actions still accessible via context menu and/or main menu, where the respective keyboard shortcuts were also listed. No need to compromise. Just make it customizable using a consistent framework.
There is a subtlety here. Having a configurable UI requires that all the buttons and menu entries have a somewhat consistent behavior among themselves. That isn't the case sometimes.
For example, if the GUI can have more than one instance of the same view open, toggle buttons for view modes become specific to individual view instances. Putting those into a global toolbar is wrong.
