In emacs 23 there was an option where we can select the word with mouse and using cntrl+s we can paste that word to search. Unfortunately this is not working in emacs 25. I didnt change the configuration file . I took the emacs code from the git hub and compiled. I am using Centos6.4 version
I have already tried this
(setq select-enable-clipboard t) and (x-get-selection-value)
But none of it helped me
You could simply (!) select the word with the mouse and type M-w C-s RET C-y RET C-s C-s
Here are the details:
