Keymaps

I use Sublime Text keymap with a few tweaks:

• Basic completion: Tab. With the auto formatting function, I do not need to use Tab to indent. Thus, Tab can be used to trigger completion. And when the completions pop up, I can press Tab again to confirm the completion candidate, very convenient.
• Find Action: the ultimate keyboard shortcut deserves F1 (inspired by vscode)
• Rename variable name: F2 is used for renaming file names in most file managers and renaming variables in vscode. For consistency, I also removed Ctrl+F2 for toggling bookmark, and bind Ctrl+F2 to introducing variables, Shift+F2 to inline variables, Ctrl+Shift+F2 to introduce constants, Alt+F2 to introduce functions (extract methods).
• Go to declaration or usage: F4 since this powerful navigation includes the function of "go to source".
• Quick documentation: F5 is near F4 (jump to source). I have poor memory and check documentation and source frequently.
• Go to symbol: F6 goes to address bar in web browsers. Thus I use F6 to navigate. And F6 is near F5 (go to documentation) and F4 (go to source). The default three-key combo (ctrl+shift+R) is too hard to remember and type.
• Find usage: F7 since it is consistent with Ctrl+F7 (find usage in current file). Although F4 can go find usages at the declaration , sometimes I still want to find other usages when not at the declaration.
• Last edit location: F8 since it is near F9.
• Toggle bookmark: F9 inspired by Yin Wang. I also set alt/ctrl/shift + F9 to show/next/previous bookmark. P.S. F2 - F9 are all used for navigation.
• Terminal: F12 since I use terminal a lot and already bind go to declaration/usage to F4. Why not keep the default? Because I want all navigation related actions are in nearby keys (F2-F9). Also, F12 in web browser opens the console.
• Complete Current Statement: C-Enter since I used it far more frequently than inserting a new line.

Fn

I bind frequently used actions to F keys, so they are easier to reach. The "Sublime" field refers to the default keyboard shorts for the real Sublime Text editor, not the Sublime Text keymap for JetBrains IDEs.

Other Tweaks

• Editor > General > Code Completion: enable "sort completion suggestions based on machine learning".
