Keyboard shortcuts
IMHO, keyboard shortcuts are needed on QWERTY keyboard devices to help justify the compromise in size of the device and the N900 has a few shortcuts that you may find useful. Did you notice in my photos that there is a real Ctrl key on the N900? Kudos to Nokia for including this since so many times we see this missing from QWERTY keyboard devices. Here are some shortcuts found in the User Guide:

General

* Ctrl + Backspace: From within an application this will take you back out to the visual task manager. (Thanks to Chanse for that one.)
* Ctrl + C: Copy text
* Ctrl + V: Paste text
* Ctrl + X: Cut text
* Ctrl + A: Select all
* Ctrl + O: Open (if available)
* Ctrl + N: Create a new item (if available)
* Ctrl + S: Save (if available)
* Ctrl + Z: Undo (if available)
* Ctrl + Y: Redo (if available)
* Ctrl + F: Open search bar (if available)
* Ctrl + Right arrow: Move the insertion point to the end of the word
* Ctrl + Left arrow: Move the insertion point to the beginning of the word

These are all great Matt, but how the heck do I select text in the first place? You can use the shift key (far left) and the directional arrows on the keyboard to select text. Or you can use the stylus and double tap for a word or triple tap for all words in a document to select.

Web browser

* Ctrl + N: Open a new window
* Ctrl + R: Reload the current page
* Ctrl + B: Open a bookmark
* Ctrl + D: Add a bookmark

Email

* Ctrl + Enter: Send a message
* Ctrl + R: Reply to a message

RSS Reader

* Ctrl + R: Refresh the feed

Screenshots

* Ctrl + Shift + P: Capture a screenshot. Warm up those fingers first to try this out. (Thanks Nokia Experts reader Matti for the tip.)

Ctrl+Shift+P = Screenshot Ctrl+Shift+X = Opens X terminal (if you have it in apps folder). IIRC there are more 3 key combos but it’s been a while since I tested it at Nokia’s Helsinki fagshipstore


Miscellaneous tips
Circle zooming: I found that a double tap on text in the web browser zooms you into that text and reflows it for the display. However, I also found you can spin your finger clockwise on the display to zoom in or counterclockwise to zoom out through multiple zoom levels. I plan to show this in a video soon so you can understand what I am talking about here, but it is pretty slick.

Browser history swipe: You can quickly view your browser history (virtual history supported) by simply swiping your finger from the right off outside the viewable display to the left onto the display.

Smart dialing with QWERTY: The N900 supports smart dialing with the QWERTY keyboard so you can simply start entering a person’s name on the keyboard and have your Contacts filtered to that name. You then simply tap the selected contact you can interact with them how you desire (call, text, Skype, email, etc.).

Make a call from Conversations: You can tap and hold on a text message conversation to see a pop-up appear so you can initiate a call with your contact.

Use Nokia Maps without data connection: Just like Nokia Maps for S60 devices you can load up maps into memory and use Nokia Maps and your GPS without a data connection when traveling.

There is a TON more in the User Guide and I’ll bring you more as I discover it and as I discover things from testing and trials with the device itself.

1. Caps Lock

To use capital letters either press

Shift once and the letter you want

or

Shift twice to turn on Caps Lock – all future letters will be in CAPITAL

you should see a message “Caps Lock on”

to turn Caps Lock off, just press shift again
2. Secondary keys (Symbols/Numbers Row)

To access the alternative keys, e.g. on “D “we have “#” press

Alt and the symbol, e.g “Alt” and “D” we get #

or

Alt twice

you should see “Fn is locked”
3. Additional Symbols Menu

Not all the symbols can be used via the tip above. e.g. [SQUARE BRACKETS]. You can access secondary symbols by pressing

Alt first and then Ctrl (maybe just start with Alt and roll your thumb to Ctrl)

You should see a grid of additional symbols
4. Highlight text

You can either use the touch screen or

Hold Shift and left/right arrow

depending on the direction of where your cursor begins.

To select a bigger block of text

Hold Shift and up/down arrow

You can then use the left/right arrow to refine selection.

If you want to highlight text in web browser that’s not in text editor

Swipe from left of the screen, an arrow cursor in a square pops up. Press it again to hold, then just drag and highlight [you can copy and paste using tips 5 and 6]
5. Copy text

After highlighting text just:

Hold Ctrl and “C” simultaneously

You may get a notification saying “Copied” across your screen
6. Paste text

After copying text :

Hold Ctrl and “V” simultaneously
7. Print Screen

This turns what you see on the N900’s screen into a picture – no third party apps necessary. Just:

Hold Ctrl and Shift and “P” simultaneously
8. Quick search for Contacts

When in desktop view, just

Start typing name of contact via keyboard

The contacts window will appear instantly
9. Instantly go back a page in the Web Browser

If you misspress a link, you might just want to go back a page instantly, and not go through the carousel of your browsing history. If so just press

Delete

And you’ll go back to the previous page.
10. Lock Phone

This technically isn’t using the keyboard but it’s a nice button shortcut alternative to the lock switch. Just press

On twice
11. Quick Multitask View

To view your multiple windows without having to press the button on screen, when you have an app running

Ctrl and Delete

You’ll instantly switch to view the live thumbnails of any open application.

This means you don’t have to exit full screen view of the web browser to switch windows.
12. Delete Lines of text without highlighting

To quickly delete whole lines of text without holding the delete button or highlighting a line of text:

Hold Ctrl and Shift and Delete [Simultaneously]

You’ll delete blocks texts one line at a time.
13. Scrolling in Web Browser

Of course, you can just swipe the screen. Alternatively you can press

Space

This scrolls down a several lines at a time.

or

Arrows

This scrolls as you hold in a particular direction
