Cross-platform browser keyboard shortcuts

As of recently I began working on a Mac-book pro and I have to get used to a keyboard with different keys and different layout. One of the most used piece of software today is a browser. I routinely use Opera but there are still sites that don’t work well with it, although it uses pretty much the same rendering engine like Chrome.

I suspect these issues arise from the fact that Chrome tends to become the new IE 6 for many web developers (i.e. : write a page, test it in Chrome, it works, the rest of browsers doesn’t matter to me, continue to next page etc.).

I consider, just like Scott Hanselman, that using the keyboard is the most efficient way to command a computer (and not the mouse / touchpad) therefore I strive to use it to the max. However, switching from OS X to the Windows virtual machine back and forth can be confusing since there are different shortcuts. For example F5 in Windows refreshes the window while in OS X it doesn’t (be it because by default you have to press Fn and then F5 in order to send F5 otherwise a media function will be sent or because this key does not do this function).

Therefore I gathered a few useful shortcut keys that work in both Windows and OS X so I can use them. Many of them work across all major browsers (IE, Firefox, Chrome, Opera and Safari). Use Command (Cmd) key in OS X and Control (Ctrl) in Windows. I’ll include only the secondary key(s) in the table below since the primary key should be held down. I am planning to update this table several times.

Function Second key Internet Explorer Opera for Windows Opera for Mac Chrome for Windows Chrome for Mac
Quit (Close) app Q  x
Close tab (window) W  ✓
Refresh tab R  ✓
Open a new tab T  ✓
Open last closed tab SHIFT-T  ✓
View source U  ✓  x
Print page P  ✓
Select all page content A  ✓
Save current page to computer S  ✓
Add to favorites / bookmark D  ✓
Find in page F  ✓
Find again G  ✓
Show history H  ✓  x
View downloads J  ✓  x
Focus the address bar L  ✓
Undo Z  ✓
Cut X  ✓
Copy C  ✓
Paste V  ✓
Open a new window N  ✓
Open a new private window SHIFT-N  ✓

✓ = available
x = unavailable
[white_space] = not yet verified

(work in progress)

Dear readers, what other useful shortcuts is this table missing?

Quick trick : Copy file path

Are you in a command line prompt and you need the full path of the file as an argument? You don’t need to type all of the path manually, not even pre-complete it using TABs. Just navigate to the file.
Here comes the trick part : hold SHIFT while right-clicking it. The context menu will look like so :


I wrote before about the SHIFT-right click so this is somehow connected.

You will then have the full path of the file in the clipboard ready to be pasted wherever you need.

Hope this helps someone! 🙂

Preparing the development environment for Java – Windows and Ubuntu

Unlike .NET development where everything is streamlined and well-aligned, starting from the OS, the framework, the tools, the IDE and all others being written by one company, in Java development you’ll experience “freedom”(1) of choice. I’ll start with a gentle introduction which the experienced may very well skip to avoid getting bored.

In order to get started developing in Java we’ll need the following :

  1. An OS. I’ll showcase Windows and Ubuntu (Linux).
  2. A Java JRE. This is the most basic component required to run Java programs.
  3. A Java JDK. The JDK or Java SDK (IBM calls it that way) typically includes the JRE plus a compiler, tools for running various types of Java programs, packaging tools, extra class libraries and many more.
  4. An IDEIntegrated Development Environment. This is typically an MDI (Multi-Document Interface) application which provides certain convenience features for the developer :
    • Syntax highlighting – keywords are displayed in a certain color, local variables in another etc.
    • Code completion – instead of having to type the whole keyword, or class identifier, a member and so on, an autocompletion prompt will appear (usually triggered by the user typing a dot or other notable event) easing your typing and avoiding typos.
    • Interactive debugging – Allowing the user to control the execution of the program by inserting breakpoints, stepping over, into or out of code, watching expressions (variables, fields etc.), modifying internal data or even (very few IDEs allow) stepping back.
    • Tracing – in case you need to inspect internal data but breaking into the debugger cancels the bug or triggers other unwanted condition or the data changes too fast, you can watch expressions in a specially designed tool window without interrupting the flow of the debugged program
    • Source control integration – allows the user to send/push/checkin/etc changes to file(s) into a repository, obtaining the latest version, comparing versions, merging, branching and many more operations
    • Visual designers – For UI modules or elements most IDEs offer some kind of preview of the developed interface, showing the developer pretty much how things will look and behave without needing to recompile, run and browsing to that particular interface
    • Packaging and deployment – Features for creating a package of the application, be it JAR, WAR, DLL, ZIP, APK etc. Furthermore many IDEs will help you push a site to a webhosting provider, cloud service and so on.
    • .. and a whole lot more but let’s try to keep things shorter

Beginning Java for .NET Developers

I’ve always wanted to learn another language and platform and being a long-time .NET developer Java seemed the closest to my knowledge and one which would seem easy to learn based on what I already knew.

I’ve put off this for various reason along the last 3-4 years, most of which laziness was chief.

Recently some colleagues moved from our project to another project that involves Java modules and since .NET is not a first-class citizen in my employer’s eyes I thought maybe it could serve me as a kind of an ‘insurance’ – to learn Java.

I’ve obtained (..) some ebooks (Effective Java and Thinking in Java), downloaded JDK, a few IDEs (IntelliJ IDEA and NetBeans, no Eclipse for me, thanks) and started doing HelloWorld’s and stuff like that. I noticed JavaFX (which is quite similar to WPF on which I currently work)

I’ve came across two nice comparisons of Java and .NET, written in a constructive manner (i.e. not “mine is better, na nanana”) :

Using these two articles I compiled (yes, that’s the original meaning of the word :P) a PowerPoint slideshow.

Then I thought there might be other (.NET developer) colleagues that might be interested in my research and gave an internal presentation based on the slideshow and expanding each item by talk.

I thought I should share it with everyone so here it is (download here) :

I’ve written about Java / C# differences before, and I might continue that series in the near future, with practical examples and counter-examples.
