How to build Keys installers for OS X and Windows:

Instructions below are for use on a OS X machine.

Prerequisite: Download Bitrock InstallBuilder (http://installbuilder.bitrock.com/download.html)

1. Put appropriate application files in correct folders to build installer. (This setting may be change in Tools/VSCOKeys.xml)
   • For OS X app generated from Xcode, VSCOKeys.app, place .app file in Build/ directory
   • For Windows app generated from Visual Studio, VSCOKeys.exe, place .exe file in Build/VSCOKeys/ directory
2. Open Terminal and run Tools/BuildInstallerOnOSX.sh, both OS X and Windows installer will be built
3. Installers can be found in Build/, zip files and they are ready to distribute

For setting on installer, such as build directory and naming of installers, changes can be made to Tools/VSCOKeys.xml.

1. Open the sampleLayout.keysjson file in a text editor of your choice (you may edit this file directly or create a new file with the extension .keysjson) to create your own layout.

2. To find the correct values for input, please use the Layout/keymap.json and Layout/toolkitlistlr4.json for reference. Change the key value and the name of the adjustment in adj (e.g. Saturation). Use keymap.json to find the imtxcode that maps to the desired key on your keyboard. Refer to toolkitlistlr4.json for the adjustment names and values.

    Layout/sampleLayout.keysjson Example:
        Line 10 sets `Q` to the preset "C - Fuji 160C from Film 01"
        Line 11 sets `W` to decrease saturation by 1
        Line 12 sets `E` to increase saturation by 1
        Line 13 sets Ctrl   `W` to decrease exposure by 1
        Line 14 sets Ctrl   `E` to increase exposure by 1
