Mac OS has the worst UX design. Use Synergy + remap Ctrl and Cmd in setting + remap Ctrl and Cmd in iterm2. Use Alt-tab with search (beta build). Keycastr, Karabiner, Maccy, yabai, Whichspace make Mac OS half usable. Note that Karabiner does not work with Synergy unless the Mac is the host. I had to enable repeating keys and disable window opening animations in the terminal, and disabled globe key changing input source, and enabled passwordless sudo + unsigned binaries for yabai.
Replace nvim with helix, ranger with nnn and zsh with fish + fzf. Because who can bother to remember configs? 0-config with sane defaults is the future.
Use n (function in fish) to invoke nnn with auto-dir entry disabled and cd on quit. Use np like in file (np) to file-pick with nnn. Run ndr to file-pick into Dropover for drag-and-drop, or dr /file/path. Within nnn type ;d to dump selected into Dropover.
Press ta,td, ts in nnn to display/undisplay folder sizes. I installed plugins as instructed, and many things for live preview, including pistol from Go. Press ;<Enter> to choose which plugin to use, ;m to open Marta at current dir and ;p for preview-tui. Note that previewing images with viu in tmux in iterm is pixelated (half-blocks) because tmux sucks (there's a fork with sixel I haven't tried).
I also have my own nnn fork to add "force yes" to cp/mv prompts. Selecting a file copies the path into clipboard, and we can use C-G to paste file path into the open file dialog in Mac.
Run "open" to open in Finder. Use fish_add_path to add to $PATH (I had to add $GOPATH/bin for Go). Press <Esc>-e to edit prompt in editor. Press <super>-<left> to move back in dir history. My own functions: use mant <command> to open man page in Skim, and abrew to replace brew (adding arch -arm64 to brew).
I hardcoded cursor shape line by printf "\e[6 q" in the fish_prompt.
Check bind | rg fzf to see the binding in fish with fzf. Fish does not allow auto-completing hidden files (stubborn author). So fzf is the next best. Use cdpast to cd to past directories with fzf (I parse strings from dirh so be careful if that changes).
Helix is awesome. clipboard-yank is nice.
I also made F2 in finder and marta open iterm2. Also C-M in Finder to open marta. Play with C-p and C-P in marta.
iterm2's preferences is stored in ~/Library/Preferences like other programs. I modified the setting "dimming for inactive panes". Also I set <Super>-= to open iterm2 in Guake style.
Press C-? to open help menu search for GUI apps.
Press <Super>-T to float and <Super>-t to toggle sticky + topmost for window with yabai. Use yabai -m query --windows | jq to find window information.
Remember that for reverse search to work in LyX we need to start lyxserver by specifying lyxpipe in path preferences. Press Ctrl+Shift while clicking in Skim to activating synctex.
Reminder that DarkReader makes Duckduckgo slower. Deactivate it for DDG.
Snapdrop is awesome for sharing files locally.
In Vimium, press >> to move tabs.
For Zotero, I use zotfile for file management and Better Bibtex. In zotfile preferences, be careful not to confuse between "Base directory" for linked attachment (should be a Dropbox folder), and "Data Directory location" (which should be local and synced by Zotero). Also remember to go into zotfile preferences and change the Location of files setting to the Dropbox folder.
For tmux, C-b I the first time it starts to install plugins. Then C-b ? for keybindings, C-b % to split, C-b <Space> to change split layout, right-click and choose "Zoom" to temporarily zoom without moving panes, and C-b ! to break the current pane into a new window. Custom keybind: C-b @ to add a pane from other windows into current window. I added C-c C-c to change tmux's current dir.
Install neovim-remote as I use it for single-instance.
Watch this to use/configure astronvim. Use plugins/user.lua to add plugins (add lazy = false to always load). Check plugins/mason.lua to install more LSP.
:Bufferize <command> to view output of command in another buffer. Use :SudaWrite to sudo write. C-] to jump into help tags. Use <Space>fk and <Space>fC for user keymaps and ex+plugin commands, and <Space>? for built-in keymaps. za to toggle fold. <space>fw to find words by telescope and :Spectre to find + replace. <space>fk and search for "split" and "buffer" to work with windows and buffers. <C-w>L to move window to right. <space>N to use nnn as file picker. <space>lt to toggle LSP diagnostics. <space>tv to open terminal and <C-\><C-n> to enter normal node in terminal.
Type <space>fh and search for "surround.usage" to learn how to use nvim-surround. In particular [ adds a whitespace gap while ] doesn't. Use built-in vi" and va" to select all between quotes (or including quotes), and <space>fr to choose from registers to paste.
Pressing q: will triggle cmdwin editing (':h comdwin'); keep pressing C-c to quit. Press C-n and C-p during snippets to jump to next / prev positions. Be careful to check that jsregexp (used for transformation) is working for LuaSnip by using _hex snippet in latex. See here to learn about transformations.
For latex and vimtex, check help of 'vimtex and friends'. Use cse to change surrounding environment. See this series for more help.
