So I am looking for a region-wise command deleting all this .. With the result $\left[\left(\partial_{t}\Phi\right)^{2}-\left\vert \nabla\Phi\right\vert^{2}\right]^{\frac{1+K}{2K}}$: (defun my-delete-all-whitespace-region (beg end) (interactive "r") (query-replace " " "" nil beg end nil nil)) Seems to be a very simple solution, but maybe too simple? Any comments? Uwe Brauer -- I strongly condemn Hamas heinous atrocities on Israel, especially the despicable pogroms. I strongly condemn Putin's war of aggression against Ukraine. I support to deliver weapons to Ukraine's military. I support the NATO membership of Ukraine. I support the EU membership of Ukraine. https://addons.thunderbird.net/en-US/thunderbird/addon/gmail-conversation-view/
