Classic Selection

Author: Tyler Spivey
Version: 1.0
This addon reverts the behaviour of NVDA+f9 and NVDA+f10 that was introduced in NVDA 2016.3.

The new behaviour has some disadvantages. Text can't be copied without being selected (and thus moving the cursor), where that's available. For places it's not (example the console), it adds an extra press of NVDA+f10.

Place Markers

Author: Noelia, Chris.
Version: 9.0
This addon is used for saving and searching specific text strings or bookmarks. It can be used  on web pages or documents in NVDA's browse mode. It can also be used for saving or searching strings of text in multi-line controls; in this case, if it's not possible to update the caret, the corresponding string will be copied to the clipboard, so that it can be searched using other tools. The plugin saves the specified strings and bookmarks to files whose name is based on the title and URL of the current document. This addon is based on SpecificSearch and Bookmark&Search, developed by the same author. You should uninstall them to use this one, since they have common keystrokes and features.
