Using the Smart Editor, you can edit geometry by entering the coordinates. I altered the coordinate tool (default) to use the Web Mercator (no TKWKID needed)
1) select item in smart editor.
2) identify the correct location with the coordinate tool in the lower left corner. highlight and copy the coordinates
3) choose the xy option under edit geometry
4) paste the coordinates. cut the longitude, paste it in the next field.
5) this moves the point. save edit.
with degrees, but switching to lat then long in the display for convenience, and also adding more numerals for precision. This allows for a quicker edit.
