I modify a bit to fit Thinkpad that do not have an individual Pause Key (for example, Yoga 12, X230, X1 Yoga etc.)
-
swap shortcut key for "clear screen" and "toggle visibility".
-
for "redo last undone stroke", change the modify key from Shft to Ctrl
On Ubuntu, to build deb package
sudo apt-get install --no-install-recommends git build-essential dh-autoreconf debhelper cmake libgtk-3-dev libappindicator3-dev
git clone -b Yoga12 https://github.com/maxchendt/gromit-mpx.git
cd gromit-mpx
dpkg-buildpackage -b -us -uc -i
cd ..
sudo dpkg -i gromit-mpx*.deb
Then, the hotkey is F10, and undokey is Pause. In my Yoga 12 (In Yoga 12, Fn+P==Pause, Fn+B==Ctrl+Pause==Break)
- F10: toggle painting
- Ctrl+F10: clear screen
- SHFT+F10: toggle visibility
- Fn+P: undo last stroke
- Fn+B: redo last undone stroke
Gromit-MPX is a multi-pointer port of the original Gromit annotation tool by Simon Budig.
It enables graphical annotations with several pointers at once and is A lot faster since it uses the XCOMPOSITE extension where available. Also, it does not inhibit Drag-and-Drop like the original Gromit tool.
Gromit-MPX (GRaphics Over MIscellaneous Things) is a small tool to make annotations on the screen.
Its main use is for making presentations of some application. Normally, you would have to move the mouse pointer around the point of interest until hopefully everybody noticed it. With Gromit-MPX, you can draw everywhere onto the screen, highlighting some button or area.
Similar tools for MS-Windows include DemoHelper (GPLv2 also), or proprietary tools like ZoomIt and ScreenMarker. For Compiz, there is also the Annotate plugin, and the much-flashier Firepaint (paint fire on screen) plugin.
