tools, Web

Go to recent tab in Chrome

For a long time I have been searching for such feature in Chrome, but I could not find anything default. And it was difficult to understand, as it is so obvious for a developer. Windows has it (Alt + Tab), Resharper has it (Ctrl + ,), visual studio without plugins has it, same to Sublime Text, vim etc. But not Chrome, a default development tool for most of web developers. At the same time there are extensions, but most of them work far from what I expect. Below I would like to share what useful I have found. Both are fine, but for sure not flawless.

Ctrl + Tab MRU


This is the one I like the most. I have it bound to Ctrl + comma. That means that a combination Ctrl + comma, comma take me to the second recently used tab. It’s obvious, but actually this is the first extension I have found, that supports it.

The bad? Several times it had problems to render the list correctly. On the other hand I tried to reproduce it while writing this blog post and I couldn’t.

Quick Tabs


This one is more advanced, as it allows to search in usage history, recently closed and bookmarks. Unfortunately Ctrl + comma, comma, comma does not work as expected (but still it’s worth to have because of searching functionality).

What about you?

Do you have your own solution for that? I would really like to know if there is something better or at least if there is another useful alternative.


Chrome tips part 1 –selectors


Howdy! After some time I’d like to start with some JavaScript stuff.

Today’s browsers give us excellent opportunity to debug our pages with the one and only Web language which is JavaScript. Best example of that tool is Chrome console which gives us more than could be described in any post. As probably each of us knows, the console opens after pressing F12.


$$ alias

The most common usage for the console is jQuery programming – we can easily traverse the page searching appropriate element or just testing selectors before scripting. The scenario complicates when there is no jQuery included.

Google Chrome console treats $ as an alias for document.getElementById and the result of such queries are far from the desired outcome. Fortunately there is a nice alternative for it which is “$$” alias.

$$ is alias to document.querySelectorAll function that does pretty similar work as jQuery.find method. So everytime I feel the lack of jQuery I use this thing with success. Remember that it doesn’t implement all the selectors that jQuery has (like :first, :even) for argument/classes queries it is enough.


As jQuery.find method replacement we can also use “querySelectorAll” method.

$x alias

Another great tool traversing the document to find some element is $x method. It uses XPath istead of css selectors. It’s good new especially for people who can do more with XPath than with jQuery.


How about ability to deal with iframe’s?

$$ and $x does not search for the content of “iframe” element. To do it you have to switch the search context. To do it with $$ once more you have to use the full name of querySelectorAll method but in context of specific “iframe” document:


In case of $x it’s is slightly different – you have to pass context as a parameter:


You have to remember, that this kind of scripting have to adhere crossframe-scripting policy – domain of the frame should be the same as parent context’s domain.
