ideavimrc | IntelliJ IDEA的VIM键位配置，快速配置USTC源

I'm trying to recreate some of https://github.com/tpope/vim-commentary function's in IdeaVim.

I've tried various mappings in my .ideavimrc, like for example:

I'm using PyCharm2018.3.
I want to create some shortcut in my ~/.ideavimrc
But it seems that pycharm vim plugin don't support :call command.
Here is my ~/.ideavimrc

I'm used to using https://www.vim.org/scripts/script.php?script_id=2703 for replacing a text object in Vim and I'm now in the process of recreating some of this functionality in IdeaVim.

I'm using these mappings in my vimrc:

The nifty CTRL-G on Mac, which selects the next occurence of a word, does not work when IdeaVim is activated. So for quite a while, I've just lived with disabling IdeaVim, every time that I want to do a multi-selection as such. But I use it more and more. Are there a work-around, to get it to work?

... Or can I do it VIM-style somehow?

Concrete example

If I have something like this:

I'm trying to trigger (to use) the IdeaVim multi cursor plugin: https://github.com/JetBrains/ideavim#emulated-vim-plugins -> multiple-cursors

In the github docs we have commands: , , , g to trigger/use this plugin, but I'm not able to make this plugin working at all...

I've added in my .ideavimrc set multiple-cursors.

Am I missing something?

I'm using OSX (if that's important).

When in insert mode in IntelliJ, typing < takes timeoutlen time (defaults to 1000ms, which is sane and useful for many other commands; changing timeoutlen to 10ms makes < basically immediate).

When in insert mode in Vim, typing < is immediate.

:imap < shows me no results, either in IntelliJ or in Vim.

How can I determine why IntelliJ is delaying this keystroke? How do I fix this?

I have my ~/.ideavimrc symlinked to my ~/.vim/vimrc, but I don't have any plugins installed. I have some custom functions defined that don't seem to do anything, but none of them use the < in their mappings.

When I type imap in ideavim, I get this:

I use the IdeaVim plugin in various JetBrains products, mostly Idea and RubyMine. I am also working on several PCs, and set up a new dev environment quite often.

I can keep most of my settings and installed plugins in sync quite well across installations by using my JetBrains Account and the Settings Sync plugin, but the Vim Emulation settings added by IdeaVim are not synced.

This means that I have to reconfigure the shortcut conflicts every time I use a new JetBrains IDE or move to a new machine - not too much work, but I would still like to avoid it.

I am aware that the IdeaVim plugin saves its settings (including the ones mentioned above) in the file ~/.IntelliJIdea2018.2/config/options/vim_settings.xml, but this file is not synced by Settings Sync. I am also aware I can use .ideavimrc to customize shortcuts (and I can sync that using some dotfile manager) but to my knowledge there is no way to configure the shortcut conflicts settings in that file.

Is there a way to sync the Vim shortcut handler settings as pictured from one machine to the other?

I want Cmd-A (the macOS Command key, plus A) to select all text in visual mode, so I can e.g. indent or delete it using vim commands, Just like it does in MacVim. By default, it selects all text, but vim commands don't work on it.

I've put the following in .ideavimrc:

I made some changes to my .ideavimrc and I want IntelliJ IdeaVim to reload the file. I can obviously close and reopen IntelliJ, but that sucks.

How can I re-source my .ideavimrc without restarting IntelliJ?
