I install sublime text 3 and this bundle for mathematica: https://github.com/dehowell/mathematica-tmbundle.
However, when I text edit under the Mathematica mode, I have shortkey conflict issues mainly with three commands, Documentation for Current Word (control + H), Execute current statement / selection (shift + enter), and Execute current document (command + R). All these 3 shortcuts have been already taken by default in sublime text. For example, (control + H) is replacement in sublime.
I tried to modify the user keymap in sublime text, but it does not work. I think the right way is to modify that bundle posted on GitHub.
Can anyone help me how to fix this? I want to use this textmate bundle because the bundle for sublime text is really bad.
You can change the shortcuts if you set keyEquivalent in the corresponding .tmCommand file to another value.
The original shortcut for "Documentation for Current Word" can be found at this line: https://github.com/dehowell/mathematica-tmbundle/blob/master/Commands/Documentation%20for%20Current%20Word.tmCommand#L15
The syntax is easy, just use set whatever letter / key you want and use one / two / three of the following modifiers: ^ (Control), ~ (Option), @ (Command)
