I would like to add several coordinates at specific British National Grid Easting and Northing values. I know this can be done by bringing in a .csv, but I want to know is there a way to manually enter the numbers in QGIS 3.4, and then the point moves to that location ? I've read that in QGIS 2.x there was a plugin called Numerical Vertex Editor that doesn't seem to exist for 3.x ?
In QGIS 3.x, create a point, choose the node tool, right-click on a snapped point and select Vertex editor. A new panel appear and you can enter the true coordinates.
There is a neat plugin that does a fantastic one-dialog job, Lat Lon Tools. Would be great if it was Core.
