Keyboard shortcut to search for selected/highlighted text

In Chrome, you can highlight some text on a web page and use the right-click context menu to open a google search for the selected text in a new tab.

It would be super convenient if I could access this feature using a keyboard shortcut instead of the right-click menu. I've tried searching for existing extensions and also scoured the list of existing keyboard shortcuts here: https://support.google.com/chrome/answer/157179?hl=en

Does anybody know a way to accomplish this?

This will work while in Chrome:

First highlight some text
Hit CTRL+C - This copies the text
Hit CTRL+T - This creates a new tab and makes it the focus
Hit CTRL+V - This pastes the text in the Omnibox (Chrome defaults the cursor there)
Hit Enter - This will search the text in the Omnibox

Want to automate it? Use AutoHotKey to make it an automatic macro using CTRL+Alt+S Use this script::

^!s::
  Send ^c
  Send ^t
  Send ^v
  Send {Enter}
Return

FYI, I tested this script and it works in Chrome.

I have two answers for this in AHK as well.

This is global applicable anywhere (not only in chrome). Just select text and press Windows+G

#g::  ;;Google selected text
   Send, ^c
   Run, http://www.google.com/search?q=%Clipboard%
Return

One is this from my answer here. Select Text and press Windows+Shift+G. This is different in that it just gives you a link on the clipboard.

; Search google for the highlighted word
; then get the first link address and put it on the Clipboard

^!r:: Reload

#+g::
    bak = %clipboard%
    Send, ^c
    ;clipboard = %bak%`r`n%clipboard%
    Query = %clipboard%
    wb := ComObjCreate("InternetExplorer.Application")
    ;wb := IEGet()
    wb.Visible := false
    wb.Navigate("www.google.com/search?q=" Query)
    While wb.readyState != 4 || wb.document.readyState != "complete" || wb.busy ; wait for the page to load
      sleep 100
    ; loop % (Nodes := wb.document.getElementById("rso").childNodes).length
    ;     Links_urls .= (A_index = 1) ? Nodes[A_index-1].getElementsByTagName("a")[0].href : "`n" . Nodes[A_index-1].getElementsByTagName("a")[0].href
    ; Msgbox %Links_urls%

    Nodes := wb.document.getElementById("rso").childNodes
    First_link := Nodes[0].getElementsByTagName("a")[0].href
    Clipboard = %First_link%
    TrayTip, First Link on Google Search, %First_link% `r`n Ctrl+V to paste the link
return

Based on what Parivar Saraff has suggested here, here is a 3 in 1 AutoHotKey Script:

                                    ;For example:

    ;If you highlight "This is a test sentence", and then hit that HotKey once, it'll make it all UPPERCASE ("THIS IS A TEST SENTENCE").
    ;Hit the HotKey again, it'll convert it to lowercase ("this is a test sentence").
    ;Hit it again and it'll convert it to Sentence case ("This is a test sentence"). (First letter is capitalized, rest is lower-case).
    ;Finally, hit it one more time and it'll convert it to Mixed case, or what I often call, "camel-case" ("This Is A Test Sentence"). (Each word is capitalized).

Apparently, pressing S after activating the context menu on a highlighted text will do just that (Chrome 78 here). The context menu can be opened with Shift+F10 or with the dedicated "context menu" button on your keyword.

These two shortcuts can be combined into one using AutoHotKey:
