As if you need another possible approach....
Turn off all Layers with the Text you want, or if that's not viable with your Layering setup, Use HIDEOBJECTS to hide all the Text you want. ERASE everything else (!) [temporarily, of course]. Turn back on or un-hide the Text parts. SAVE to another drawing [not QSAVE or any so-called "Save" icon that really gets you QSAVE, and not SAVEAS]. That will make another drawing just like the current state of the present one, but will leave you in the present one. UNDO the ERASE-ing.
An advantage [or possibly a disadvantage, depending on your purpose] of the SAVE approach: The resulting drawing will have all the Layers, Text and Dimension and Mleader and other Styles, Block definitions, loaded Linetypes, Limits, Layouts, Viewports, etc. of the present drawing [just no drawn content other than the Text], which will not necessarily always be the case with either the Copy/Paste or WBLOCK approaches.
