Shift-s - search the highlighted selection directly inside a search engine (defaults to google).

In copy mode:

highlight file.pdf and press o - file will open in the default PDF viewer.
highlight file.doc and press o - file will open in system default .doc file viewer.
highlight http://example.com and press o - link will be opened in the default browser.
highlight file.txt and press Ctrl-o - file will open in $EDITOR.
highlight TypeError: 'undefined' is not a function and press Shift-s - the text snipped will be searched directly inside google by default

How can I change the default "o" key binding to something else? For example, key "x"?

Put set -g @open 'x' in tmux.conf.

How can I change the default "Ctrl-o" key binding to "Ctrl-x"?

Put set -g @open-editor 'C-x' in tmux.conf.

How can I change the default search engine to "duckduckgo" or any other one?

Put set -g @open-S 'https://www.duckduckgo.com/?q=' in tmux.conf

How can I use multiple search engines?

Put:
