Editing Editing midi in reaper using osara (section)

== accessing and using the midi filter window ==

Reaper has a [[Chapter 13: Manipulating and Editing MIDI Items#13.6 The MIDI Editor Window|midi filter]] (described on detail in the second paragraph). When using the NVDA screen reader focus is not automatically changed when the "filter events..." option from the view menu is used. 

note: these instructions are becoming obsolete, since a recent osara update has attempted to address this issue (thanks to programmer Alexey Zhelezov)

There are two ways to get to that window:
#After you choose the option filter events from the view menu, do a physical move of your mouse or trackpad up and to the left and you should be able to hear the title of the filter window, or parts of the filter window  being announced. Click once with the left button when you do and that should focus the window.
#If you are more comfortable using the object navigation functions of NVDA, when you choose the filter events... option from the view menu, you should move two times to the parent object. Press numpad shift 8 on your numeric pad if you are using a desktop, or NVDA shift up arrow if you are using a laptop. Then, move to the two previous objects by pressing NVDA+4 on the numeric pad if you are using a desktop, or NVDA shift left arrow if you are using a laptop. Then you can move focus to that window by pressing NVDA shift minus on the numeric pad if using a desktop or NVDA shift backSpace if using a laptop.
#make your changes or customizations to the filter, then press shift plus space bar or route the mouse (with NVDA slash on the numeric pad in desktops, or NVDA shift M in laptops) on the clear filter, add to selection, set selection buttons.
#press escape when you are finished to close the window.
