It seems that for some reason, when selecting a new cell, the content (by default "none") gets placed in the clipboard.  I guess we need to investigate this.

However I don't think there is ever going to be a fast way to do what you want using any GUI.  The GUI is really for doing single, one off tasks.

For a lightning fast way to add value labels to many variables, just use a line like:

ADD VALUE LABELS /v1 to v500 1 = "yes" 2 = "no".

Problem:

a) When I try to copy  word "yes" or "no" from Libre Calc 7.0.. into pspp v.1.4.0, as Value label in Variable e.g. X1, then OK.
When I try to go to Variable X2 to add the same Value label eg. "yes", then the word "none" is copied instead of "none".
---I tried to copy a random word from my web brower. Same behaviour
----I Tried to copy with mouse or by keyboard short cut. Same behvaioru

b) An "enhancement: It is inconvinient to have 200 vars "yes/no" to write for each one of these "yes/no" instead of mass copy a single value over many sheet cells.
It is inconvinient to have to change the decimal spaces for 500 vars, in order to appear "normally" instead of mass copy a single value over many sheet cells.
