Additionally, Web pages can be scrolled with Space or +Shift+Space on the left half alone, to enable taking notes with the right hand +at the same time. + +* Other than Right Shift (which I seldom use), mods aren't rebound on layers. + +* Likewise, Backspace is not rebound on layers to avoid having to let go of +layer-switch keys to correct mistakes. ## Default layer @@ -11,20 +26,97 @@ more details on the principles that went into the layout. ([KLE](http://www.keyboard-layout-editor.com/#/gists/08d9827d916662a9414f48805aa895a5)) +* The alpha keys are a standard QWERTY layout, no funny business there. + +* Tab and Backspace are in familiar locations from my row-staggered boards +(almost all of which use HHKB-style split backspace). + +* Likewise, the Ctrl key is in the same place as on my row-staggered boards +(where I've been remapping Caps Lock as Ctrl since before even using QMK). + +* There are two Shift keys, because I do use Right Shift on occasion (even +though I'm predominately a Left Shift-er). + +* Lower and Raise layer-switch keys are below the left and right thumb, +respectively, when resting my fingers on the home row. + +* Space and Enter are on the big thumb keys so they're easy to press. + +* Alt is on the left so I can navigate back (Alt+Raise+H) and forward +(Alt+Raise+L) without having to uncomfortably hit two thumb keys on the same +half. This puts Super on the right by the process of elimination. + +* Escape shares a mod-tap key with Ctrl, which is convenient for Vim, but not +something I'm totally in love with, as even after tweaking `TAPPING_TERM` I +still get occasional spurious Esc taps. (I might move Esc up a key and put Tab +on a layer, but that'd take some getting used to....) + ## Lower layer  ([KLE](http://www.keyboard-layout-editor.com/#/gists/c3fba5eaa2cd70fdfbdbc0f9e34d3bc0)) +* This could also be called the "symbol layer". + +* Shifted numbers are bound in their usual positions on the top row. + +* Hyphen/Underscore and Equals/Plus are in the right index- and middle-finger +columns for easy reach. They share the same relative position as on a +row-staggered keyboard, and the shifted versions are physically above the +unshifted versions as a mnemonic device. + +* Brackets and braces are placed below the parens for easy recall. Once again, +the shifted versions are on the home row and the unshifted versions are on the +bottom row. + +* Forward Slash/Pipe and Backtick/Tilde fill out the remaining positions on the +right half, with the same relative positions as on a row-staggered HHKB layout. +And yup, the shifted versions are above the unshifted versions. + +* Caps Lock is bound in the same position as on an HHKB, for lack of an obvious +better location. + +* Some extra keys are placed on the bottom row of the left half, ensuring every +key on a TKL has a binding. + +* The left-half home row is reversed for future use. (It's free real estate.) + ## Raise layer  ([KLE](http://www.keyboard-layout-editor.com/#/gists/08b44355d4ca85d294bad9e2821f91d7)) +* This could also be called the "number layer". + +* Unshifted numbers are bound in their usual positions on the top row. + +* Arrow keys are on VIM-style HJKL keys. + +* Home/End and Page Up/Page Down are in the same column as the arrow keys, but +translated down one row. (This means that the comma and period keys are not +bound on the number layer, which makes data entry a bit funky. I might add a +dedicated numpad layer to compensate.) + +* Function keys F1–F10 take up most of remaining space on the left half, with +F11 and F12 spilling over to the right half. (This puts the most used function +keys (F1–F5) on the home row.) + +* Insert and Delete are on the rightmost column, because there didn't seem to +be a better place to put them. + ## Adjust layer  ([KLE](http://www.keyboard-layout-editor.com/#/gists/77e7572e077b36a23eb2086017e16fee)) + +* Media keys are centered around the ESDF cluster, just like I arrange them on +row-staggered keyboards. (It's even more sensible with columnar stagger.) + +* The navigation keys are replaced by RGB controls. Again, this mirrors the +positioning I use on my row-staggered keyboards. + +* Finally, reset keys live at the top-left corner of the right half where it's +reasonably hard to press them by accident. |
