I have searched through the Preferences Panel (and used the Search facility in the Shortcuts panel) but I cannot find any way to attach keyboard shortcuts to the following buttons.

Is this possible? I don’t like the default Rotate, Scale, translate “R”, “S” and “T” functions because it doesn’t seem possible to constrain them to a particular axis (but I am new to Blender) - please tell me if there is.
Any help appreciated!
Thanks
Richard
