I have put his notes below.. I also tried with nto much success to try and figure out why orca did not work with thunar though it claims to have great gtk support. Please find notes below and hope it is helpful. export SAL_USE_VCLPLUGIN="gtk" GTK_MODULES="gail:atk-bridge" before starting a GTK program makes it aware of orca as screenreader. You need to start orca as well, of course. The panel containing the menu (lxpanel in our case) will send the "highlighted" menu item to orca automatically if the two variables mentioned before are set before starting lxpanel. The tricky part is to pop up the menu without the mouse. Unfortunately, lxpanel does not have a "hotkey" for this on its own, but the command "lxpanelctl menu" will notify lxpanel to show the menu. Now you add this command to the window managers hotkey list (which is different in compiz-fusion and metacity), and you are there. Once the hotkey (Alt-F1 in Knoppix) is pressed, lxpanelctl menu will be called, and the menu pops up. I did not find a way yet to browse through the dock icons in lxpanel, though it must be possible somehow, since using the mouse will focus the icons and lets orca speak them. Maybe, just the internal link between icons and a hotkey for selecting them is missing. pcmanfm works quite well with orca, though the "desktop background" version of it is not very talkative. If you start the windowed version of pcmanfm, you can switch between canvases with eithger TAB or the cursor keys (sometimes it's not very intuitive to understand which one to use). It should be possible, yet I'm unsure how to make the desktop manager part of pcmanfm put the focus on the first icon on the desktop. Once one item has the focus, you can browse through the desktop icons with the cursor keys. surely pcmanfm could need some accessibility enhancements concerning hotkeys and their documentation. in regards to accessing the panel, The only way I found so far is the "lxpanelctl" command which is to be called by the window manager. Alt-F1 pops up the menu in Knoppix. The hotkey modifications for compiz-fusion and metacity concerning the lxpanel menu is present in /etc/X11/Xsession.d/45knoppix. Here is an excerpt: -- case "$STARTUP" in *lxde|lx*) # Need to change Alt_F1 and Alt_F2 hotkeys in order to make LXDE menu accessible sed -i -e 's/as_main_menu_key *=.*$/as_main_menu_key = Disabled/g' \ -e 's/as_run_command0_key *=.*$/as_run_command0_key = <AltF1/g' \ -e 's/as_command0 *=.*$/as_command0 = lxpanelctl menu/g' \ "$HOME/.config/compiz/compizconfig/Default.ini" 2/dev/null gconftool --type string \ --set /apps/metacity/global_keybindings/panel_main_menu disabled \ --set /apps/metacity/global_keybindings/panel_run_dialog disabled \ --set /apps/metacity/global_keybindings/run_command_1 '<AltF1' \ --set /apps/metacity/global_keybindings/run_command_2 '<AltF2' \ --set /apps/metacity/keybinding_commands/command_1 'lxpanelctl menu' \ --set /apps/metacity/keybinding_commands/command_2 'lxpanelctl run' ;; *) # Change Alt-F1 back when not running lxde sed -i -e 's/as_main_menu_key *=.*$/as_main_menu_key = <AltF1/g' \ "$HOME/.config/compiz/compizconfig/Default.ini" 2/dev/null gconftool --type string \ --set /apps/metacity/global_keybindings/panel_main_menu '<AltF1' \ --set /apps/metacity/global_keybindings/panel_run_dialog '<AltF2' ;; esac -- Of course this can also be set manually in gconf-editor (metacity/gnome) or ccsm (compiz-fusion).

Whilst I have quietly pushed accessibility (well, maybe not so quietly) as a part of lubuntu, we now need a bit of help off this team. Our specification of the minimal hardware it will run on cannot be broken, nor can our commitment to pre i686 processors. <a href="https://wiki.ubuntu.com/Lubuntu" target="_blank">https://wiki.ubuntu.com/Lubuntu</a> From a general chat to our head of development on lubuntu, he is of the opinion that if the code is really (and I mean really) tight, that it would be possible to include within the very tight constraints that we are committed to be able to uphold the inclusion of accessibility and has agreed that we should really strive to attain this. We are short of devs who can dedicate resources to this task, so I ask that any of you who can assist do so. I'd really like to see lubuntu 11.10 come out with as much accessibility as is possible on " A Pentium II or Celeron system with 128 MiB of RAM is probably a bottom-line configuration that may yield slow yet usable system with Lubuntu" So, once you've all had your heart attacks and say it cannot be done... the ones who go "hmmm, that is actually possible.." Please make your selves known.
