How to input location of selected Vertex using keyboard only Anyone with sufficient mouse and chair miles will confirm that learning the keyboard short-cuts for frequently used operations vastly speeds up a workflow. 

Today I realized that there are things I use the mouse for that should be doable solely from a keyboard context. One of these things is moving a selected vertex using the Transform toolbar.

My question is: How to enter a new coordinate for an existing selected vertex without using the mouse or the transform toolbar? Preferably absolute Global / absolute Local .

Another reason why absolute entry would be welcome
Another example, but this affects multiple selected vertices, is setting the X component of a bunch of vertices to be locally some absolute value. Especially useful when a mirror modifier needs the center vertices to line up nicely and their median X is not 0. Now the way is to S ,X to restrict the axis, then numeric 0 to unify them (sets them all to the median of their x component), then mouse over to the transform panel and set the median x to 0.
SHIFT + S and U Cursor to Center
SHIFT + S and T Selection to Cursor
G 1.5 Tab - 1 Tab 1.2 Enter


First step can be skipped when the 3D cursor is already at the center.
