On Xinet 2020.7, it was impossible to use hotkeys to select all of the text in the search field within Pilot v20.7.x. For example, when the cursor was in the search field, using Cmd-A (macOS) would do nothing.
This was identified as a defect and was solved as a part of the release of Xinet 2021.5 Server and Portal. With this release, Pilot (2021.5.408) was released as well, which addressed this issue. The hotkey functionality has been restored.
