Configure Tap Zones and use them as buttons and sepearte scroll wheels. Ive detailed it here
Using Easystroke to perform like Scrybe Gesture Workflows — Searching and Shopping
First install xsel sudo apt-get install xsel
we will be using a command type
Example: searching for "obama" in wikipedia in the command entry type:
google-chrome "http://en.wikipedia.org/w/index.php?title=Special:Search&search=`xsel -p | tr [:space:] +`"
now choose a gesture, lets choose a shape w
highlight a word and perform the gesture and you should be there.
to get any other website search perform a search query "test" in there search engine i,e, youtube which gives the result http://www.youtube.com/results?search_query=test&aq=f
now replace "test" with xsel -p | tr [:space:] + (with those little brackets)
then your command will be
google-chrome "http://www.youtube.com/results?search_query=`xsel -p | tr [:space:] +`&aq=f"
make sure you use the brackets for your url.
any other search engines can be done using this.
Mapping mouse buttons to keyboard shortcuts
If you have a mouse button that you don't need, you can use easystroke to remap it to any command or keyboard shortcut. Just add the button as an additional button (or use the gesture button if you don't want to use gestures). Since you don't want to use the button for gestures, select "Instant Gestures" on the bottom of the button dialog. To assign an action to the button, just press the button when recording a new gesture. To assign a modifier to the mouse button, you can use the "Ignore" action type.
Emulating a scroll wheel using a button
If you don't have a scroll wheel, you can make easystroke emulate one by pressing a button and moving the cursor. Add the button as an additional button of type "instant gestures" as above, and record a new gesture by clicking the button, then change the action's type to "Scroll".
xte is a handy little command-line tool that can emulate key presses and mouse clicks. In Debian/Ubuntu, it can be found in the xautomation package.
You can use xte to execute a squence of key presses. For example, the following command will go 5 tabs to the right in firefox:
xte 'keydown Control_L'; for i in `seq 1 5`; do xte 'key Page_Down'; done; xte 'keyup Control_L'
Here's a command that will enter today's date into a document:
xte "str `date +%D`"
wmctrl allows you to do various window manager actions from the command line. A useful feature is "wmctrl -a <str>", which will switch to a window containing the string <str> in the title. For example, to activate a firefox window, and start firefox if there is no such window, use the following command:
wmctrl -a Firefox || firefox
GUI testing frameworks
GUI testing frameworks such as dogtail and LDTP offer much better control over applications than what is possible by emitting key strokes, but they're also more difficult to use and they also require assistive technologies to be enabled. If you have a good example of what is possible with those tools, please add it here.
Wacom Tablet PCs
Turn TPCButtons off, so that you can click the button on your pen without having to tap the pen at the same time. This can be done using the command
xsetwacom set stylus TPCButton 0
or, permanently, by adding the line
Option "TPCButton" "off"
to the last "InputDevice" section pertaining to your tablet. Note that in order for this to be persistent through suspend or switching VTs, you'll need the latest linuxwacom driver from git (relevant commit). See also [FeatureAdvancedGestures].
Don't use Rotate Scripts
There are tons of applications out there that allow you to change screen resolution and rotation. However, as a tablet user you will also need tell the wacom driver to rotate pen input. So people ditch these applications and replace them by something much worse: Custom-made rotate scripts that must be used if you want to your pen to be usable after rotate - very annoying and cumbersome to set up.
But Xrandr is perfectly capable of notifying applications of screen changes, so a much better solution is to have a tiny daemon that performs the necessary actions whenever the screen is rotated. The wacomrotate daemon is an example of this: It will both rotate the pen and, if you're running gnome, adjust the orientation of subpixel smoothing, which will make fonts less blurry. You can find the source at github, and packages for jaunty and karmic in one of my PPAs
If you're looking for a replacement pen, you might want to check out the pen that comes with the Fujitsu Stylistic ST Tablet PCs. You can get 2 for 50 dollars (link), which seems a little steep, but is actually less than you would pay for most other replacement pens. It fits into the slot in Toshiba tablets (but it might be a little hard to get out). Unfortunately, it's too big to fit into Thinkpads. Okay, why am I recommending this pen? Well, it's the only pen I'm aware of that has two buttons on the side, which makes life a lot easier under linux (but note that easystroke allows you to emulate a "third" mouse button, but in any case, additional mouse buttons never do any harm). It's also white, which makes it a lot easier to spot if it falls in the cracks of your couch.
Useful Tablet PC apps
These applications have nothing to do with easystroke per se, but I've found them highly valuable, so I'd like to spread the word.
- xournal is a great note-taking application. It supports PDF annotation and can take advantage of the full digitizer resolution.
- cellwriter is a handwriting input panel/onscreen keyboard with a very pleasant and intuitive user interface.
- Grab and Drag is a firefox add-on that makes scrolling with a pen a breeze. It also works for thunderbird, by the way.
- Many Tablet PCs come with high-resolution displays (145 dpi in case of the x61t and the LE1700) that can cause strain when used at the default font settings. The NoSquint firefox extension allows you to set a default zoom setting for all web pages and separate settings for specific sites.
