From 058149656c62a174b9e74854d7252395fdb47f8c Mon Sep 17 00:00:00 2001 From: Florent Nuttens Date: Mon, 7 Oct 2024 18:59:02 +0200 Subject: [PATCH] feat(kanata): add HRM-optimized navigation layer MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## HRM friendly S-tab/tab S-tab and tab stay on the homerow while playing nice with Ctrl and Alt mods. ## Add cross-platform quit shortcut on HRM nav layer @qut → [Q] - @qut allows closing apps on any OS (C-q on Linux, A-f4 on Windows, etc.), optimizing muscular memory - it is more coherent to map @qut on [Q] @pad → [A] - @pad thus mirrors @fun on the right hand - allows using the numpad’s arrow keys without locking the layer (layer-while-held) ## Map esc/del on [A]/[V] The goal is to allow escaping and deleting using the left hand only. --- README.md | 12 ++ img/vim_hrm_navigation.svg | 248 +++++++++++++++++++++++++ kanata/deflayer/navigation_vim_hrm.kbd | 54 ++++++ kanata/kanata.kbd | 1 + 4 files changed, 315 insertions(+) create mode 100644 img/vim_hrm_navigation.svg create mode 100644 kanata/deflayer/navigation_vim_hrm.kbd diff --git a/README.md b/README.md index 4e65b96..60e0480 100644 --- a/README.md +++ b/README.md @@ -157,6 +157,18 @@ without holding the key until escaped with Alt or AltGr.
