Use a different key binding

Introduction

As a Neovim user, you're likely familiar with the various key bindings and modes that come with the editor. However, sometimes these default settings can lead to unexpected behavior, especially when working with complex codebases. In this article, we'll explore the potential drawbacks of remapping gh, gH, and g<C-h> to do nothing, with a focus on avoiding select mode.

Understanding Select Mode

Before we dive into the potential drawbacks, let's quickly review what select mode is and how it works. Select mode is a feature in Neovim that allows you to visually select text in the buffer. When you enter select mode, you can use various key bindings to select text, including v, V, and gv. However, select mode can sometimes be triggered accidentally, leading to unexpected behavior.

The Accidental Trigger

You may have experienced this yourself: you're typing away, and suddenly, you accidentally trigger select mode. This can happen when you press gh or gH by mistake, or when you use g<C-h> to move the cursor to the previous character. When select mode is triggered, Neovim will replace the character under your cursor with the character you're trying to insert, and then switch to insert mode. This can lead to a mess of characters, especially if you're working with complex code.

Remapping `gh`, `gH`, and `g<C-h>` to Do Nothing

To avoid this issue, you can remap gh, gH, and g<C-h> to do nothing. This will prevent Neovim from triggering select mode when you press these keys accidentally. To do this, you'll need to add the following lines to your Neovim configuration file (usually ~/.config/nvim/init.vim):

nnoremap <silent> gh <NOP>
nnoremap <silent> gH <NOP>
nnoremap <silent> g<C-h> <NOP>

The Drawbacks

While remapping gh, gH, and g<C-h> to do nothing may seem like a simple solution, there are some potential drawbacks to consider:

Loss of functionality: By remapping these keys to do nothing, you'll lose the functionality of these key bindings. For example, gh is typically used to move the cursor to the previous character, while gH is used to move the cursor to the previous line. If you remap these keys, you'll need to find alternative ways to perform these actions.
Confusion: If you're working with a team or collaborating with others, remapping gh, gH, and g<C-h> to do nothing may cause confusion. Others may not be aware of the remapping, and may accidentally trigger select mode when trying to use these key bindings.
Customization: Remapping gh, gH, and g<C-h> to do nothing may limit your ability to customize your Neovim experience. For example, you may want to use these key bindings for other purposes, such as moving the cursor to a specific location or triggering a custom plugin.

Alternatives to Remapping

If you're concerned about the potential drawbacks of remapping gh, gH, and g<C-h> to do nothing, there are alternative solutions you can consider:

Use a different key binding: Instead of remapping gh, gH, and g<C-h> to do nothing, you can use a different key binding to trigger select mode. For example, you can use gs or gS to trigger select mode.
Customize your Neovim configuration: If you're concerned about losing functionality or customization options, you can customize your Neovim configuration to work around the issue. For example, you can create a custom plugin to handle select mode or create a custom key binding to trigger select mode.
Use a different editor: If you're finding that Neovim is not meeting your needs, you may want to consider using a different editor. For example, you can use Vim or another editor that offers more flexibility and customization options.

Conclusion

In conclusion, remapping gh, gH, and g<C-h> to do nothing can be a simple solution to avoid select mode in Neovim. However, there are potential drawbacks to consider, including loss of functionality, confusion, and customization limitations. By understanding the potential drawbacks and exploring alternative solutions, you can make an informed decision about how to customize your Neovim experience.

Final Thoughts

Q: What is the purpose of remapping `gh`, `gH`, and `g<C-h>` to do nothing?

A: The purpose of remapping gh, gH, and g<C-h> to do nothing is to avoid triggering select mode in Neovim. Select mode can be triggered accidentally, leading to unexpected behavior, such as replacing the character under your cursor with the character you're trying to insert.

Q: What are the potential drawbacks of remapping `gh`, `gH`, and `g<C-h>` to do nothing?

Confusion: If you're working with a team or collaborating with others, remapping gh, gH, and g<C-h> to do nothing may cause confusion. Others may not be aware of the remapping, and may accidentally trigger select mode when trying to use these key bindings.
Customization: Remapping gh, gH, and g<C-h> to do nothing may limit your ability to customize your Neovim experience. For example, you may want to use these key bindings for other purposes, such as moving the cursor to a specific location or triggering a custom plugin.

Q: What are some alternative solutions to remapping `gh`, `gH`, and `g<C-h>` to do nothing?

A: Some alternative solutions to remapping gh, gH, and g<C-h> to do nothing include:

Use a different key binding: Instead of remapping gh, gH, and g<C-h> to do nothing, you can use a different key binding to trigger select mode. For example, you can use gs or gS to trigger select mode.
Customize your Neovim configuration: If you're concerned about losing functionality or customization options, you can customize your Neovim configuration to work around the issue. For example, you can create a custom plugin to handle select mode or create a custom key binding to trigger select mode.
Use a different editor: If you're finding that Neovim is not meeting your needs, you may want to consider using a different editor. For example, you can use Vim or another editor that offers more flexibility and customization options.

Q: How can I remap `gh`, `gH`, and `g<C-h>` to do nothing in Neovim?

Q: What is the difference between `gh` and `gH`?

A: gh and gH are both used to move the cursor to a specific location, but they have different behaviors. gh moves the cursor to the previous character, while gH moves the cursor to the previous line.

Q: Can I use a different key binding to trigger select mode?

A: Yes, you can use a different key binding to trigger select mode. For example, you can use gs or gS to trigger select mode.

Q: How can I customize my Neovim configuration to work around the issue of select mode?

A: Some other key bindings that you should be aware of in Neovim include:

v: Visual mode
V: Visual line mode
gv: Visual mode with the same selection as the previous visual mode
