My wife wanted to do a search and replace to replace 1/2 with ? and 3/4 with ? but we couldn't paste that with Ctrl-V or middle-click (in X).
So I used vim to edit the lyx document. Also I wanted to replace '1/3' with the corresponding evil red text. How can I paste in ERT in the Find dialog? (My workaround was to use it to Find each place and I manually removed and pasted with Ctrl-V right in my document.)
